Notes:
An automated micro batch analyzer (AMBA) system is described. The sample is introduced into an air-tight reaction chamber (a polypropylene microcentrifuge tube) by a loop injector made from two three-way valves by flowing gas. Reagents/diluents are introduced into the chamber from pneumatically pressurized reservoirs provided with on-off valves. A microprocessor-controlled timer controls valve status and thus provides control of delivered volumes. Gas bubbles are introduced through the bottom of the chamber to perform mixing; the mixed liquid is then discharged into an optical detector via a bubble gate by superincumbent pressure. The bubble gate allows the data-acquisition system to collect data only when liquid is actually in the detection cell. For simple fast reactions, throughput rates of 210 samples/h could be obtained.
