ABSTRACT:
A measuring part measures the absorbance spectrum of an effluent fluid sample from a chromatograph in a constant cycle, and a base line calculating part calculates a base line including absorbance values on both ends of a designated wave number range with respect to every absorbance spectrum data as measured. A peak area calculating part calculates the peak area of the absorbance spectrum in the designated wave number range on the basis of the decided base line. A chromatogram is obtained by time change of the calculated peak area. Thus, it is possible to eliminate influences by other functional groups and fluctuation of the base line in an absorbance analyzer.
