ABSTRACT:
A chemical analysis system including a suction unit for sucking an amount of a sample from a sample vessel and determining whether or not the sucked sample is of a sufficient amount for analysis. If the sucked amount is of a sufficient amount, it is transferred directly to a reaction vessel for mixture with a reagent in a measurement unit for analysis. If the sucked amount is of an insufficient amount, it is initially transferred to a temporary sample storage unit in order to detect the amount of insufficiency and then is transferred to the measurement unit for mixture with the reagent and also with a dilution solution which is added to the insufficient sample in an amount determined by the amount of insufficiency determined in the temporary sample storage unit. Then, the analysis of the previously insufficient amount of sample is performed taking into account the amount of dilution solution added to the previously insufficient amount of sample. A control unit is providing for controlling the overall operation of the system.
