PURPOSE:To suppress an error and economical loss to a min. degree, by performing statistical discrimination to measured data one after another in a real time and detecting the mistake of a specimen or the abnormality of an analyser at an early stage. CONSTITUTION:Plural measured data X of an analyser are inputted to a re- inspection and discrimination means 1 to which a limit value discrimination means 2 and a sum-of-product operation means 3 are provided. The discrimina tion means 2 compares measured data X (x1-xn) of each item and a limit value G (g1-gn) preset at every inspection item every time each item is inspected. When said measured data is fallen in the limit value, the measured data from the discrimination means are inputted to the sum-of-product operation means 3 which, in turn, statistically perform sum-of-product operation using the predetermined linear discrimination function C (c1-cn) to the input data on the basis of a predetermined formula in a real time. The normality, abnormal ity and the requirement of re-inspection of measured data are estimated and discriminated and the results are respectively outputted. |
