ABSTRACT:
In order to improve a signal-to-noise ratio of an optical detector with a light source and a photodetector of ordinary performance, light is applied from an ultraviolet lamp 6 which is provided on one side of a capillary cell 4 while light generated from the capillary cell 4 is received by an array photodetector 14 provided on the other side thereof. A lens 18 makes positions on the capillary cell 4 to correspond to those on the array photodetector 14. A data processing part 20 temporarily stores corrected and incorporated detection outputs, and calculates integrated averages while displacing time bases so that those of the same sample portions are overlapped with each other.
