ABSTRACT:
A spectrophotometer provided with: a sample changer for holding a plurality of samples to be analyzed, each of which is given an identification code, and positioning a selected one of the samples for measurement; means for setting a measuring wavelength for each of the identification codes of the samples; means for setting an identification code for the measured data of each of the samples; means for setting a coefficient to be used for processing the measured data of each of the samples together with an identification code; means for setting an operation expression composed of the identification codes of the measured data of the samples and the identification code of the coefficient; means for storing the data obtained by measuring each of the samples with the corresponding one of the wavelengths set for the sample held by the sample changer in correspondence with the corresponding one of the identification codes of the measured data; and means for reading out the data stored in the storing means and the coefficient set in the setting means in accordance with the identification codes of the measured data and the coefficient which constitute the operation expression set in the setting means, and performing an operation for data processing in accordance with the operation expression.
