Abstract
PURPOSE:To give warning at the time of holding an error in a result, by taking two measuring points and deciding the propriety of the result of analysis from a ratio of measured values of standard sample and sample to be measured at said points. CONSTITUTION:A changeover switch 2a is connected to a (a) at measuring time of standard sample and measured value at a time after the elapse of set time from a measuring part 1 is stored in a standard value storage part 3 after injection of reaction reagent. The switch 2a is then switched to (c) and the measured value at a time after the elapse of another set time is stored in a standard value storage part 3a. The switch 2a is connected to (b) in the case of sample to be measured and the measurements are carried out two times in the same way to give the measured value to an operation part 4. A ratio of data of the standard sample and sample to be measured at each point of time is obtained by the part 4 and the data are compared with each other. The result of analysis is then decided as right when the data are in the near range with each other. In this way, the result of decision of correction of errors together with that of the analysis of sample to be measured are displayed on an output part 6.
