Abstract

PURPOSE:To display whether working curve is good or bad basing on many measured values, by operating a correlative coefficient of concentration and measured result. CONSTITUTION:An electric signal is generated in accordance with the concentration of object substance by introducing a sample of analysis into an analyzer part 1 and this electric signal is operated in the relation of primary proportional function by a signal output operational processing part 2. The value of the previously indicated concentration of the sample is input in a correlative coefficient operational processing part 3 and the correlative coefficient is operated in combination with the value obtained from the part 2 and then, the result is displayed on a indication part 4. Hereby, the error of analysis result including both apparatus and operation of analysis is expressed by only one numerical value and an administration can be executed.
