PURPOSE:To improve the accuracy by arranging a sample distributing nozzle adapted to ony distribute a sample to be inspected to a reactor corresponding to specified measuring items among a plurality of reactors and a nozzle for distributing a pure water to a reactor to which the sample is not distributed. CONSTITUTION:An automatic chemical analyzer is composed of a sample distribution nozzle 3 adapted to only distribute a sample to be inspected to a reactor corresponding to specified measuring items among a plurality of reactors, a pure water distribution nozzle 15 for distributing a pure water to reactors to which the sample being inspected is not distributed, a pure water distribution pump 14 for discharging the pure water from the nozzle 15 and the like. With such an arrrangement, a pure water is allowed to be distributed to the reactors to which the sample is not distributed. This not only prevents drying in the sample passage system including reactors but also enables the cleaning of the reactors, a flow cell and the like thereby improving the measuring accuracy remarkably. |
