Abstract
A spectrophotometer has not only an optical system for irradiating a cell with light having a specified wavelength, a detector for detecting light received from the cell and a data processor for precessing data based of detection signals from the detector, but also a cell sensor and a cell identifier for detecting whether a cell is mounted and, if so, the kind of the mounted cell, a program memory which stores validation programs for carrying out validation tests and a validation controller for retrieving from the program memory one of the stored validation programs corresponding to the identified kind of the cell and carrying out the retrieved validation program.
