Method and instrument for automatic discrete analysis

Abstract

Abstract PURPOSE:To save manpower for remeasurement by bringing a sample and reagents into reaction to obtain a measured value and retreat the sample automatically according to the defectiveness of the measurement results by a control device. CONSTITUTION:The sample of a specimen vessel 1 of a sample table 2 is put into a reaction vessel 18 of a reaction table 8 by a pipetting mechanism 6. The reagents 22, 23 are put into the reaction vessel 18 and are brought into reaction with the sample. The absorbancy of the sample is then measured by a spectroscope 12. The measurement operation is controlled by a controller 28. A systematic trouble (S) with which the measured values are continuously defective and a random trouble (R) with which the measured values are contingently defective are judged by the controller 28 at this time by the controller 28 and the cause thereof is indicated. The measurement conditions, etc., are corrected to the normal conditions, etc., and the measurement is made again in the case of the trouble (S). The sample is diluted with a diluent and the measurement is made again after the sample is diluted with a liquid diluent if, in the case of the trouble (R), the cause is, for example, the abnormally high activity of the sample. The sample is, therefore, automatically treated and the measurement is made again according to the cause of the defect of the measurement results. The time and manpower for the remeasurement treatment are thus saved.
