Abstract

PURPOSE:To facilitate the manipulation and increase the reliability of analytical values, by using a memory with concentration data input device, and an operator to calculate according to the method of least squares. CONSTITUTION:A memory 2 equipped with concentration data input device 6, and an operator 7 to calculate according to the method of least equares are disposed between an input signal converter 1 and a display device 5. By this constitution, a signal from an absorption photometer is converted into a digital signal by the input signal converter 1, and is stored in the memory 2, together with the concentration data of standard substance solution added to the specimen inputted from the concentration data input device 6. When all data are prepared, they are inputted into the operator 7, and the concentration of the substance contained in the specimen before addition of the standard substance solution is calculated according to the method of least squares, and the calculated value is displayed in the display device 5.
