Claim 7:
8. The abnormality determination method according to claim 7, wherein
the determining presence or absence of an abnormality includes determining 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, determining 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 determining 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.
