ABSORBANCE DETECTOR, CHROMATOGRAPH, AND METHOD FOR MANAGING LIGHT SOURCE REPLACEMENT TIME

WIPO Patent Application WO/2020/148842

A1

This absorbance detector is provided with a light source, a flow cell, a photodetector, and a detector control unit. The light source has a first storage unit. The flow cell receives light generated by the light source. The photodetector detects light transmitted through the flow cell. The first storage unit stores, in advance, characteristic information for identifying the light source. The detector control unit includes a second storage unit, a determination unit, and an updating unit. The second storage unit stores the characteristic information of the light source and the replacement time of the light source. An acquisition unit acquires the characteristic information stored in the first storage unit. The determination unit determines whether the characteristic information acquired by the acquisition unit and the characteristic information stored in the second storage unit match. When it is determined by the determination unit that the characteristic information acquired by the acquisition unit and the characteristic information stored in the second storage unit do not match, the updating unit updates the characteristic information stored in the second storage unit to the characteristic information acquired by the acquisition unit, and updates the replacement time stored in the second storage unit to the current time.
