Abstract

1,111,630. Counting-apparatus. TECHNICON INSTRUMENTS CORPORATION 12 Dec., 1966 [5 Jan., 1966], No. 55478/66. Heading G4D. A liquid sample is analysed by passing a first portion through a flow-cell in one direction and a second portion through the flow-cell in the opposite direction. Blood samples in tubes 10 are connected sequentially to a pumping system whereby a first portion is mixed in coil 62 with air and a diluent before being passed through a valve system 94 in the position shown so as to pass downwards through a flow-cell 96. Photoelectric apparatus 98, 100 operates a counter 102 and recorder 104 to register the number of all cells, effectively the number of red cells. A second portion is mixed in coil 84 with acetic acid and tergitol to destroy the red cells before being passed through the flow-cell 96 in the opposite direction (Fig. 2, not shown), the photo-electric apparatus, with adjusted sensitivity, now counting only the white cells. The tubes may be cleansed between samples from a source 30.
