    [0001] TECHNICAL FIELD The present invention relates generally to the field of the analysis of products that can be sucked in, inhaled or inhaled by a user, and corresponding diffusion devices. BACKGROUND OF THE INVENTION .
    [0002] It relates more particularly to a test machine adapted to analyze at least one diffusion device of a product that can be sucked in, inhaled or inhaled by a user of the diffusion device and / or to analyze a product diffused by such a device. of diffusion. The machine allows a physico-chemical or sensory analysis of the diffused products having physiological, therapeutic or other properties. The invention also has applications for qualifying the operating state of all types of diffusion devices for such products. Non-exhaustively, examples of use of such devices may be the "vaping" of e-liquids for the electronic cigarette, the dissemination of medical products, health products or well-being, etc. BACKGROUND ART Existing test machines are currently mainly intended for sampling for analysis of conventional cigarette fumes. They are called "smoking machines" in the field concerned. The e-liquid smoking machines known to date are rare, restricted to market-specific, often artisanal, broadcasting devices and do not faithfully reproduce the conditions of use of the devices by the users. PRIOR ART A known system for the study of electronic cigarettes is, for example, the CETI 8 system from Cerulean, the term "CETI" being 3022632 2 the acronym for "Cerulean e-Cigarette Testing Instrument". This system allows an operator to select the form, volume and duration of puffs of the diffused product, as well as the number and spacing between puffs for capturing vapors at a filter pad for the purpose of controlling an off-line chemical analysis. However, this system does not make it possible to qualify the diffusion devices, or to test and characterize new products with other physiological or therapeutic properties. CN 103512827 discloses a method and apparatus for testing the performance of an electronic cigarette.
    [0003] SUMMARY OF THE INVENTION The invention aims to provide a versatile and multifunctional system for the qualification of all types of products that can be aspirated, inhaled or inhaled by a user and corresponding broadcast devices.
    [0004] For this purpose, the invention proposes a machine for analyzing at least one diffusion device of a product that can be sucked in, inhaled or inhaled by a user of the diffusion device and / or for analyzing a product diffused by such a device. broadcasting device, comprising: a control automaton; A controlled atmosphere inlet compartment, with at least one support adapted for mechanical holding of the diffusion device in said inlet compartment; at least one actuator associated with the diffusion device, and controlled by the automaton so as to produce specific mechanical actions on the diffusion device; at least one regulating device for the temperature and / or hygrometry of the atmosphere in the input compartment, operating under the control of the automaton; - a controlled atmosphere outlet compartment; at least one member for regulating the pressure, the temperature and / or the hygrometry in the outlet compartment, controlled by the automaton so as to obtain pressure conditions in the atmosphere of the outlet compartment; , temperature and / or hygrometry determined; at least one ventilation member associated with the diffusion device and arranged to cause a flow entering the diffusion device from the inlet compartment and to simultaneously discharge into the outlet compartment a flow coming out of the diffusion device, said ventilation unit being controlled by the automaton so as to produce a ventilation having specific characteristics; and at least one analysis equipment enabling the analysis of a flux diffused by the diffusion device which is discharged into the output compartment, in order to qualify the operating state of the diffusion device or to characterize the broadcast stream. The invention has advantages relating to the functional aspect of the machine, but also to its adaptability to the different possible uses of the tested devices, thanks to its ability to reproduce the environment of use and the behavior of the users during the use of the devices. The machine makes it possible to simulate the action of the users on the devices and the operating situations of the devices. For example, it is possible to accurately reproduce, during the tests, the stresses applied to devices in a real situation of oral and / or nasal inhalation, active and / or passive. Reproducible constraints include: - inhalation and expiration at a controlled rate, pressure, duration and frequency, simulation of the temperature of the oral and / or nasal hygrometry, - activation of the devices, 30 - 1 inclination and movements of the devices printed by the user, for example from 90 ° to + 90 ° or from 0 to + 180 ° with respect to the horizontal, unlike the systems of the market allowing only to carry out tests with the horizontal, 3022632 4 - etc. The machine makes it possible to study the life cycle of the devices and the adequacy between the devices and the products used. Brief Description of the Drawings Other features and advantages of the invention will become apparent upon reading the following description. This is purely illustrative and should be read with reference to the accompanying drawings in which: - Figure 1 is a diagram of a diffusion device of the type of an electronic cigarette; FIG. 2 is a block diagram of a test machine according to the principle of the invention, in an exemplary embodiment having 9 lines of analysis arranged in groups of 3 lines of analysis; Figure 3 is a diagram showing an exemplary embodiment of a group of three lines of analysis of a test machine according to Figure 2; and, - Figure 4 is a diagram showing an exemplary embodiment of a group of three lines of analysis used for the calibration of a test machine according to Figure 2.
    [0005] DETAILED DESCRIPTION OF EMBODIMENTS Diffusion is a physical process that is characterized by a change of state from a liquid or solid product to a diffused state, i.e., in the form of a gas or gas. 'a cloud of extremely fine particles. Depending on the particle size distribution in the cloud, it is called fumes (particles with a size of about 0.1 to 0.5 microns), vapors (particles with a size of about 0.5 to 0.8 microns). ), mists or "spray" (particles with a size of about 0.8 to 10 microns), or aerosols (particles of about ten microns or more). Thus, for example, a vaporizer is a diffusion device (or diffuser) for converting certain liquids into vapors.
    [0006] The proposed test machine is described below, by way of non-limiting example, in its application to the test of diffusion devices of the type of an electronic cigarette. An electronic cigarette, also called e-cigarette, is a thermal vaporizer. It produces aromatic vapors from a liquid solution under the effect of heat. Such liquids are also called e-liquids, or e-fluids. The vaporization temperature is between about 250 and 300 ° C, while the diffusion temperature is the device output temperature of between 30 and 60 ° C. However, the invention should not be limited to this example, since the proposed machine is usable for other types of diffusion devices, such as, for example: - other types of thermal vaporizers, - vaporizers by compression, decompression vaporizers, vaporizers by chemical reaction producing a gas, vaporizers by aerosol generation, solid particle generation diffusers, liquid particle generation vaporizers, diffusers by impregnation in a solid, 20 - etc. In general, the machine also makes it possible to test products that can be diffused by all types of broadcasting devices, whether portable or not. The products may be in liquid form, in the form of gel or paste, or in the form of solids capable of being vaporized or otherwise diffused by the devices. The electronic cigarette simulates the act of smoking by a system of production of flavored vapor and optionally loaded with nicotine in dosages ranging from 0 mg / ml to 20 mg / ml. This vapor is likely to be aspirated, inhaled or inhaled by the user.
    [0007] With reference to the diagram of FIG. 1, an electronic cigarette 100 essentially comprises an electric battery 101 and an atomizer 102 fed by the battery 101. The atomizer itself comprises a heating resistor 103, a reservoir of diffusable product or e- liquid 104 and a tip 105 intended to be worn in the mouth by the user to suck puffs of the diffused product. In some cases, the e-cigarette 100 further includes an activation button 106 allowing the user to control the production of steam or vaporization.
    [0008] The autonomy of the electronic cigarette depends on the technology and the size of the battery 101. The e-cigarette 100 can be equipped with a system for varying the voltage delivered by the battery, which makes it possible to adjust the power absorbed by the atomizer 102, and thus the volume of vapor delivered. The tank 104 may be plastic, more or less reinforced. Its capacity can vary, as well as its shape, depending on the specificities of the application. The activation button may for example actuate a switch arranged between the battery 101 and the heating resistor 103 of the atomizer 102. FIG. 2 is a block diagram of a test machine according to the principle of the invention, adapted for analyzing at least one diffusion device of a product that can be sucked in, inhaled or inhaled by a user of the diffusion device and / or for analyzing a product diffused by such a diffusion device. In embodiments, the machine comprises at least one set of N analysis lines adapted for parallel analysis of a set of at least N respective associated broadcast devices, where N is an integer at least equal to three. Each line of analysis is dedicated to the testing of an associated diffusion device, for example ensuring the e-liquids vaping for the electronic cigarette, or the diffusion of medical products, health products or well-being. , or other products likely to be aspirated, inhaled or inhaled by a user of the diffusion device. In the example shown, the devices are electronic cigarettes as explained above with reference to FIG.
    [0009] In embodiments, furthermore, the N rows of analysis may be grouped into a number M of sets of N / M rows of analysis where M is an integer at least 2 and a submultiple The machine may then comprise: a number M of input chambers in the input compartment, each associated with N / M respective analysis lines, and a number N of output chambers in the output compartment, each associated with a respective line of analysis, Each of the M sets of N / M lines of analysis connects one of the M input chambers to a number N / M of output chambers, through one of the respective diffusion devices to be tested. In an exemplary embodiment illustrated in FIG. 2, the machine has nine lines of analysis adapted for testing nine broadcasting devices. In other words, in the example shown N equals nine (N = 9). In the example shown, in addition, the analysis lines are arranged in groups of three analysis lines respectively dedicated to testing three groups of three devices each, the device triplets 11-13, 21-23 and 31 respectively. -33. In other words, in the example shown M is equal to three (M = 3). The machine comprises an input compartment 1 thus having three input chambers 10, 20 and 30, each associated with a triplet of analysis lines, ie, the lines associated with the device triplets 11-13, 21-23 and 31-33, respectively. Each analysis line comprises a support for mechanically holding the diffusion device associated with said analysis line in the corresponding inlet chamber of the inlet compartment 1. The machine shown also comprises an outlet compartment 2 having nine chambers. 111, 112, 113, 121, 122, 123, 131, 132 and 133, each associated with a respective line of analysis. Each of the three sets of lines of three lines of analysis connects one of the three input chambers 10, 20 and 30 to three of the output chambers, namely the triplets of output chambers 111-113, 121-123, and 131-133, through one of the diffusion devices to be tested 11-13, 21-23 and 31-33, respectively. In addition, the machine comprises N ventilation members namely the ventilation members 211, 212, 213, 221, 222, 223, 231, 232 and 233. They are each associated with one of the diffusion devices 11, 12, 13, 21, 22, 23, 31, 32 and 33, respectively. They are arranged between the inlet compartment 1 and the outlet compartment 2. Each of the ventilation members 211, 212, 213, 221, 222, 223, 231, 232 and 233 associated with the diffusion devices 11, 12, 13, 21, 22, 23, 31, 32 and 33, respectively, is arranged to cause a flow entering the diffusion device from the input compartment or input chamber associated with the device, and simultaneously to repress a flow out of the diffusion device in the outlet compartment or the outlet chamber. The ventilation members may be arranged to ventilate from the inlet compartment to the outlet compartment, or vice versa. They can be ordered individually, or in groups. Thus, in the example shown, each of the triplets of ventilation members 211213, 221-223, and 231-233 sucks since (or, depending on the direction of the ventilation, flows into) the inlet chamber 10, 20 or 30, respectively. The grouping of lines within a set of N / M lines 15 as explained above makes it possible to accelerate the number of tests carried out simultaneously, and to respond to a recommendation from the OFT (the French organization for the prevention of Smoking) presented in the report on the cigarette of May 2013 (http://fwww.oftaasso.fr/docatel/Rapport e-ciciarette VF 1, ndf: page 67) which recommends to repeat the tests three times per device, and per set of 20 test conditions. In addition, this makes it possible to quickly identify the failure of a device or an analysis line, abnormal deviations of the results obtained for an analysis line compared to other lines of the same group. This makes it possible to qualify an operating difference between the devices under strictly identical operating conditions within a line triplet, in particular by virtue of the common input chamber for the triplet. According to the principle of the invention, the inlet compartment 1 is controlled atmosphere. More particularly, in the case of clustering of the analysis lines as previously discussed, the atmosphere in each compartment 1 inlet chamber is controlled. This is achieved by at least one member for regulating the temperature and / or humidity of the atmosphere in question. This member operates under the control of a control device 3, or PLC. In FIG. 2, the commands generated and sent for this purpose to the input compartment 1 by the automaton 3 are represented by the arrow 301. This makes it possible to control the temperature and / or the hygrometry of the flow entering the diffusion devices tested in order to increase the relevance of the tests carried out and their reproducibility. This also makes it possible to participate in controlling the temperature of the machine, in particular to take into account variations in its operating conditions as a function of time (for example, raising the temperature during operation). The inlet compartment, or more particularly the inlet chambers thereof, comprise at least one support adapted to mechanically hold each of the diffusion devices. Advantageously, the inlet compartment or, as the case may be, the inlet chambers thereof, furthermore comprise at least one actuator associated with each diffusion device. This actuator can be controlled by the automaton so as to produce specific mechanical actions on the diffusion device. In FIG. 2, the commands generated and sent for this purpose to the input compartment 1 by the controller 3 are represented by the arrow 302. For example, such an actuator may comprise a jack arranged to modify the inclination of the device For example, the angle of diffusion of the devices is adjustable from -90 ° to + 90 °. This makes it possible to reproduce the actual conditions of use of the diffusion devices, in particular cycles of use and inclination of the device relative to the horizontal whereas in known smoking machines the devices are always arranged horizontally.
    [0010] For devices equipped with an activation button 106 as shown in the example of FIG. 1, another actuator may comprise a mini-jack with an adjustable position, enabling the actuation of each device by the automaton as a function of determined sequences. The frequency, duration and spacing between the activations of the device can thus be controlled to reproduce usage cycles in accordance with the actual usage by the users. Preferably, the actuators associated with the devices of the same group are controlled in the same way, in order to ensure the effect of triplication of the analyzes which can be sought by the grouping of the analysis lines. Alternatively, an actuator can actuate several devices simultaneously, for example all devices of the same group. The ventilation members 211, 212, 213, 221, 222, 223, 231, 232 and 233 associated with the diffusion devices 11, 12, 13, 21, 22, 23, 31, 32 and 33, respectively, can also be controlled by the controller 3 so as to produce each ventilation having specific characteristics. In FIG. 2, the commands generated and sent for this purpose by the automaton 3 to the ventilation members 211, 212, 213, 221, 222, 223, 231, 232 and 233 are represented by the arrow 303. Each organ The fan may be controlled by the controller to reproduce puffs of the broadcast product that may be actually generated by the user from the broadcast device.
    [0011] Preferably, the devices of the same group are controlled in the same way, in order to ensure the effect of triplication of the analyzes which can be sought by the grouping of the analysis lines. The outlet compartment 2 is also controlled atmosphere. More particularly, for a machine having N output chambers 20 respectively associated with N diffusion devices to be tested, the atmosphere in each of said N output chambers can be controlled separately. This is achieved by at least one regulating member of the temperature and / or hygrometry in the outlet compartment, or the outlet chamber considered of said compartment. This regulation is performed under the control of the controller 3 so as to obtain in the atmosphere of the outlet compartment conditions of pressure, temperature and / or hygrometry determined. In Figure 2, the commands generated and sent for this purpose to the output compartment 2 by the controller 3 are represented by the arrow 304.
    [0012] In one example, the regulator of the pressure, temperature and / or hygrometry in the outlet compartment 2, or in each of the chambers 111, 112, 113, 121, 122, 123, 131, 132, and 133 thereof, is controlled by the controller 3 so as to reproduce in 3022632 11 the atmosphere of said outlet compartment or said outlet chamber, pressure conditions, temperature and / or hygrometry determined from a real oral and / or nasal environment of a user of the broadcast device associated with the corresponding analysis line.
    [0013] The machine may further comprise a management unit 4 which is adapted to control the automaton as a function, in particular, of data obtained at a particular level of the M sets of analysis lines dedicated to the calibration of the machine. machine. This calibration can be based on a parameterization of the commands generated by the controller 3, as a function of 10 measurements carried out in real time at the level of the machine itself, on a batch of devices dedicated to the calibration, namely for example the devices 11, 12 and 13 of the group of devices associated with the group of lines of analysis at the top of Figure 2. In Figure 2, the parameters generated by the management unit 4 and 15 sent to the controller 3 are represented by the arrow 401. The data measured for this purpose at the outlet compartment 2 are represented by the arrow 402. In embodiments, the control unit 3 and / or the management unit 4 are produced by a integrated device comprising a computer and a human-machine interface, or via a separate device such as a programmed generic computer, or a program (software) intended to be executed by such a generic computer . In any case, the machine operates from a database relating, in particular, to the different types of possible use of the devices by the users (eg statistical data). Finally, the machine further comprises at least one analysis equipment for analyzing a stream diffused by the diffusion device which is discharged into the outlet compartment or the corresponding outlet chamber, in order to qualify the state of operation of the broadcast device or characterize the broadcast stream. Part of the analysis material can be shared for several lines of analysis, for example for the lines of the same set or group of lines. Conversely, another part of the analysis material may be specific to each line of analysis.
    [0014] In FIG. 2, the analysis data collected by the management unit 4 coming from the output compartment 2, are represented by the arrow 403. The unit 4 saves all the analysis data produced during the tests. carried out for later use.
    [0015] For reasons of readability of the drawings, the analysis equipment is not shown in FIG. 2, and will be explained below with reference to FIG. 3. Other characteristics and advantages specific to embodiments of the machine will become apparent from the following description of exemplary embodiments of the analysis lines, given with reference to FIG. 3 and FIG. 4. Considering the grouping of the analysis lines into sets of three lines in FIG. In this example, each of these figures shows the arrangement of equipment associated with a set or group of three lines of analysis. This is obviously not limiting of the invention, other groupings, or conversely the absence of grouping lines, being possible options. It will firstly be presented, with reference to FIG. 3, embodiments of a set of operational analysis lines, that is to say dedicated to the actual analysis of broadcast or 20 products broadcast by them. Next, a set of analysis lines dedicated to the calibration will be explained with reference to FIG. 4. In FIG. 3, all three analysis lines of FIG. 2 associated with the devices 21, 22 and FIG. 23. Each analysis line comprises a support for mechanically holding the diffusion device associated with said analysis line in the inlet chamber 20. In order to reproduce the actual conditions of use, the inclination of the devices 21, 22 and 23 is adjustable, for example from -90 to + 90 °, or from 0 to + 180 °, by means of an actuator 21a, 22a and 23a, respectively. It may be a jack, associated with a suitable mechanism. In the case of diffusion devices which are equipped with an activation button, such as the knob denoted 106 in FIG. 1, other actuators such as mini-jacks 21b, 22b, and 23b with an adjustable position allow the valve to be 3022632 13 automatic actuation of each device. Optionally, this activation can be controlled individually for each device. However, in the context of a tripling of the tests, identical and simultaneous activation is controlled for the three devices of the same set of devices. The actuators associated with the broadcasting devices can be controlled by the controller 3 so as to reproduce certain actions that can actually be exerted on the broadcasting device by a user of said device. The movements of the devices can be reproduced, possibly, between activation phases of the devices, or during such phases. The automaton 3 of FIG. 2 controls and regulates the temperature, the hygrometry of the flow entering the devices, through the control and regulation of the temperature and hygrometry of the atmosphere in the inlet chamber. 20. For this purpose, there is provided a temperature and humidity sensor 20a, a temperature control system 20b capable of heating and cooling the air in the chamber 20, and a system 20c for regulating the temperature. The system 20b is capable of heating and cooling the air in the chamber 20. The system 20c is able to dry and humidify the air in the chamber 20. This allows to freeze the conditions of use of the broadcasting devices throughout the tests that are carried out. In some embodiments, the inlet chamber may further comprise at least one flow inlet for receiving a determined gaseous, liquid or solid flow, and / or an ambient air flow. This makes it possible to define the physico-chemical environment in which the devices are used. Thus, the air in the inlet chamber can be standardized, for example charged with CO2. Another flow inlet may allow at least a portion of the flow diffused into the outlet compartment 2 to enter into the chamber 20 by one or more of the diffusion devices, and thereby returned to the inlet compartment. . This can make it possible to account for the natural evolution of the conditions of use of the devices during a real use, for example in a confined space such as the passenger compartment of a motor vehicle. In the example of FIG. 3, the ventilation members 221, 222 and 223 of the analysis lines associated with the devices 21, 22 and 23, respectively, are represented as being arranged in the output compartment 2. This is a non-limiting example. In an exemplary embodiment, the ventilation members 221, 222 and 223 may each comprise a pump 221a, 222a and 223a, respectively, and a three-way valve 221b, 222b and 223b, respectively. The pump and the three-way valve are controlled by the controller 3 so as, for example, to reproduce flushes of the diffused product that can be actually generated by the user from the diffusion device. The pump may be, for example, a peristaltic membrane or diaphragm pump, or any other type of pump appropriate to the application's needs. It responds for example to the following characteristics, recommended in the report of the O.F.T. aforementioned: variable flow rate: from 2 to 138 milliliters in 2 seconds; - generated depression: from -2 to -16 millibars.
    [0016] The three-way valve (suction, discharge and discharge) makes it possible to simulate the type of puffs, especially abrupt or progressive. Alternatively, the flow can be regulated with other equipment, for example one or more regulators of flow and pressure, in place of the three-way valve. The machine may comprise a temperature sensor 2a and a temperature control system 2b, arranged to control the temperature in the outlet compartment 2. The system 2b is suitable for heating or cooling the atmosphere in this compartment. This makes it possible to keep the operating temperature of the various equipment installed in the outlet compartment 2 constant, in particular the ventilation members 221, 222 and 223. The control of the temperature and humidity in the outlet chambers 121, 122 and 123 can be made individually for each chamber 3022632 15 by means of temperature and humidity sensors 121a, 122a, and 123a, respectively. The regulation of temperature and humidity in the outlet chambers 121, 122 and 123 can also be individualized at each chamber. However, in the example shown in Figure 3, a system 24 of hygrometry control (in humidification and drying) is shared between the lines. Anti-return valves 121b, 122b and 123b are disposed between the systems 24 and 25 on the one hand and each outlet chamber 121, 122 and 123, respectively. These valves are controlled by the controller 3 to regulate the hydrometry individually in each output chamber based on the information transmitted by the sensor 121a, 122a, and 123a of each of the output chambers 121, 122 and 123, respectively. This principle of shared operation is used, in the example as represented by the temperature regulation (in heating and cooling), thanks to a temperature control system 25. Although not shown in FIG. control and pressure regulation in the outlet chambers 121, 122, and 123 may also be provided. They can be individualized for each room, or shared for the three rooms of the analysis line set considered. Examples of analytical material will now be described. This analysis equipment makes it possible to analyze a flux diffused by each diffusion device 21, 22 and 23, and which is discharged either into the outlet compartment 2, more particularly into the outlet chamber, 121, 122 and 123, respectively, either in the inlet compartment 1, more particularly the inlet chambers 10, 20 and 30. It thus makes it possible to qualify the operating state of the diffusion devices or to characterize the fluxes diffused in the frame by example of the study of diffusable products.
    [0017] In embodiments, the analysis equipment may comprise temperature sensors 21c, 22c, and 23c, arranged to measure the temperature of the outgoing flow of the diffusion device 21, 22, and 23, respectively, and discharged into the compartment of the analyzer. output 121, 12 and 123, 3022632 respectively. A temperature measurement at this point qualifies the operating state of the diffusion device. Indeed, for diffusion devices which are heating devices such as electronic cigarettes, the temperature of the diffused product is a direct indication of the operating state of the device. If the diffusion device is not a heating device, the temperature of the diffused flux is nonetheless characteristic of the diffusion, so that a temperature measurement gives relevant information on the operating state of the devices.
    [0018] Analytical equipment may be adapted to allow sensory analysis, continuously or in sampled form, of the product diffused by the diffusion devices 21, 22 and 23 and discharged into the outlet chambers 121, 122 and 123 of the compartment. output 2 or the inlet chambers 10, 20 or 30 of the inlet compartment 1.
    [0019] Thus, in an embodiment as shown, the analysis equipment comprises a screen 26 in front of which the flux diffused by the diffusion device is displaced to allow a visual characterization of said flow by an operator. In one example, particularly suitable for essentially white color vapors, the screen may be black or dark in color. Conversely, if the diffused product is dark, the screen may be white or light in color. The screen can be removable, in order to be replaced each time by a screen of the most appropriate color possible according to the products broadcast. Advantageously, the screen may be associated with a lighting member 25 adapted to produce controlled lighting conditions. In embodiments, it is further possible to provide another member such as an image sensor for image capture for subsequent analysis. It can be a CMOS imager, a digital camera, a webcam, etc.
    [0020] In the example shown, the machine comprises a system 27 for recovering and processing flows. Such a system makes it possible to recover hazardous materials for humans and / or for the environment. It may be, for example, an activated carbon filter, or a bag arranged to collect all the fluxes diffused by the three diffusion devices 21, 22 and 23. It is also possible to provide such a system for each line of individual analysis. The assay equipment may further include a stream sampling member for physicochemical analysis of the product diffused by the diffusion device and discharged into the exit compartment, or individually in the exit chambers. , 122 and 123 and in the inlet compartment 1 in the inlet chambers 10, 20 and 30. The analysis equipment may also comprise a condensing module arranged to recover, in liquid form, all or part of the product diffused by the diffusion device and discharged into the outlet compartment, for the physico-chemical analysis of said product. This is useful in cases where the analysis is easier to perform on a liquid form of the diffused products.
    [0021] The analytical equipment may further comprise a sterile analytical bag arranged to capture the entire flow diffused by at least one of the diffusion devices and discharged into the outlet compartment 2. It may advantageously be a specific bag arranged at the outlet of each chamber 121, 122 and 123, or a common bag for recovering together the vapors generated by the three devices 21, 22 and 23 and in the inlet compartment 1 in the inlet chambers 10, 20 and 30 Any other analytical device necessary for qualifying the flow may be provided, in addition to or instead of the examples given above. In FIG. 4, the analysis lines of the set of the three analysis lines represented at the top of FIG. 2 are represented. These lines are associated with the devices 11, 12 and 13, and serve for the calibration of the machine. In this figure all elements corresponding to elements already described with reference to Figure 3 are not referenced again so as not to overload the figure at the expense of its readability. Note simply the ventilation members 211, 212 and 213 associated with devices 11, 12 and 13, respectively.
