Claim 4:
5. The absorbance detector according to claim 1, wherein
the abnormality determiner determines that the sample cell is contaminated at a point in time at which a continuous analysis is started in a case where the absorbance shows a decreasing trend while intensity of the reference signal shows an increasing trend each time an analysis is carried out, determines that a light amount of the light source is unstable in a case where the absorbance shows an increasing trend while the intensity of the reference signal shows a decreasing trend each time an analysis is carried out, and/or determines that the optical system is contaminated in a case where the absorbance does not change while the intensity of the reference signal shows a decreasing trend each time an analysis is carried out.
