Abstract
An absorbance detector includes a sample cell, a light source for irradiating the sample cell, a photo sensor, an optical system for guiding light emitted from the light source to the sample cell and guiding light that has been transmitted through the sample cell to the photo sensor, a reference signal acquirer configured to acquire a detection signal of the photo sensor when the sample solution is not flowing through the sample cell as a reference signal for each analysis of the sample, a calculator configured to find absorbance of the sample based on a measurement signal obtained by the photo sensor in the analysis and the reference signal acquired for the analysis when an analysis of the sample is carried out, and an analysis data storage configured to associate data of the absorbance found by the calculator and data of the reference signal to each other for storage.
