CONTINUOUS FLOW ANALYSIS

摘要

In continuous flow equipment for blood group analysis, air bubbles are introduced into the liquid flow at fittings (8, 33, 35) under control of an air valve (10). Individual samples drawn in via probes 4p, 4rc are separated by periods of bubbled flow passing on lines 231-10 to reaction manifolds 31-10. Periodically the air valve (10) is controlled to produce a recognisable code of air bubbles, thereby identifying adjacent samples in the flow. Downstream of the reaction manifolds 31-10 the code is read at the reaction detection stations (30).
