PURPOSE:To avoid a situation in which data number is limited in a memory apparatus, and prevent the measurement with the same combination by lessening the number of data number obtained by the measurement to check cross- contamination in a reagent injection system. CONSTITUTION:To search the combination of items with which a reagent injecting system is cross-contaminated, an automatic chemical analyzer is provided with a processing part 32 which starts measurement from an item in a first turn to the last including all the P types of assigned items for all of the (P-1) pieces of continuously numbered samples, assigns the measurement order of the items in order not to form the same measurement combination among the (P-1) pieces of the samples, and issues a work sheet automatically to instruct that only the first item should be measured for a next sample following those samples, a data computing part 34 which takes in the measurement results for every item from an analyzing part 30 which carriers out analysis according to the work sheet issued from the processing part 32, compares the results with a standard value, and judges whether cross-contamination occors or not, and a holding file part 36 to hold the results as cross-contamination data at the time of normal measurement. |
