ABSTRACT:
An analyzer for chemically analyzing biological samples delivers required reagents in a plurality of reagent bottles to reaction containers corresponding to analysis items. A reagent which becomes deteriorated by carbonic acid gas is registered in advance, and it is judged by a control device whether such a reagent bottle is loaded in the reagent containing chamber or not. If such a reagent bottle is loaded in the reagent containing chamber, a purge gas for sweeping-out air containing carbonic acid gas is supplied to the reagent containing chamber. The flow rate of the purge gas is controlled so as to be large during an initial period of analysis preparation stage and is then decreased.
