PURPOSE: To make it possible to reduce electric power consumption and size of a spectrophotometer and to easily carry it and to make analysis in a sample drawing place by constituting a light source of a flash lamp and constituting a detector section of plural detectors.
CONSTITUTION: A sample is put into a sample cell A and a solvent for the sample is put into a sample cell B, then a measurement is made. Signal processing is executed in a signal processing circuit 17 by the measured value: As of the n' wavelength on the side A, the measured value BR1 of the n' wavelength on the side B and the signal values obtd. from the measurement of 1W3 (1: the measurement of the measurement error component by the dark current of the diodes of the diode array detectors A and B, 2: the measurement of the difference in sensitivity between the detectors A and B, 3: the measurement of the sample), by which the absorbancy ABSn' at the n' wavelength of the sample is calculated. The reduction of the electric power consumption of the light source is made possible ≤10-4 by lighting the light source only for the time within 1W10msec.
