    1432608 Automatic analysis; preparing sample stream TECHNICON INSTRUMENTS CORP 17 May 1973 [9 June 1972] 23626/73 Heading G1B Sampling apparatus for use in automatic analysis comprises sampling means for taking into conduit 14, 24 and flowing along the conduit a stream of sample liquid segmented (both on sample offtake and by means of tube 32 in the embodiment shown) by a separating fluid immiscible with the sample liquid, fluid removing means 48, 56 in the conduit operative to remove only at predetermined time intervals a controlled volume of the stream from the conduit, the controlled volume comprising a volume of the separating fluid, and a dosage device 50, 52 downstream of the fluid removing means and connected to the conduit for introducing into the stream at the same time intervals a volume of fluid proportional to the controlled volume. In the apparatus shown, tube 32 is connected to a source of air under pressure and to accumulator 34, which releases to junction 36 at controlled intervals precise volumes of air at a pressure higher than that in reagent or diluent pump tube 30. The fitting 42 operates to remove all gas segments by line 56 and to introduce air segments via line 50 to divide the sample segments into 4. Each sample is initially taken by the offtake tube 14 in 3 portions, two "pecks" to clean the tube and a larger portion, the samples being separated by wash liquid. At fitting 42, the trailing end of a larger, measurement part of the sample is cut-off by an air segment and enclosed together with a wash liquid segment and the forward end of the next sample segment by this air segment and the next air segment, Fig. 5 (not shown). The outlet end 47 of fitting 42 is connected with distribution manifold 74 whence separate sub-streams 76 are pumped by means 78 to analytical cartridges 80.

    noJEiaeTCH through conduit 14 by means of a pumping system 12. Moreover, the volumes of liquid to be removed and the incoming gas to the fitting 9 are chosen proportional to the internal cross section of the pipeline. Thus, at the outlet of the fitting 9 in the pipeline 15 in the fluid flow, the number of individual samples flowing per unit of time increases, which makes it possible to increase the rate of fluid sampling in the analyzer block 16. Increasing the sampling rate allows for increased efficacy.
