ABSTRACT:
An analyzing apparatus which automatically and sequentially analyzes a large number and variety of chemical samples which are divided into a plurality of fractions, whereby each sample is simultaneously tested with different chemicals under suitable reaction conditions. The system operates under pressurized closed flow conditions, that is to say, the solution flow lines are compressed with an inert gas, whereby the formation of air bubbles in the flow system, oxidization of samples, reagents, the rise of noxious fumes, are prevented.
