PURPOSE:To enable the measuring of samples on optimum conditions, by setting optimum measuring time interval for the samples for measuring data of a plurality of samples obtained in the initial stage at a relatively short time interval to repeat the measurement at this time interval. CONSTITUTION:Samples of a plurality of sample cells 2a, 2b,... set in a cell 2 are switched with a driver 4 controlled by a control section 12 and automatically inserted into an optical path to measure absorbance thereof. The achieve this function, a memory 14 of the control section 12 stores a data measured, a change rate calculating means 16 calculates the change rate of the respective samples from those at the initial stage among measuring data of the memory 14 and an initial switching interval setting means 20 set a short sample switching interval at the initial stage. Moreover, a switching interval control section 18 of the control section 12 controls the driver 4 so that the samples quick in changes are switched at a short time interval, and those slow in changes at a long time interval according to a setting means 20 at the initial stage and according to a calculated value of a calculating means 16 after the calculation of the change rate. |
