Abstract:
A chromatogram analyzer which analyzes a chromatogram obtained by applying a sample containing an analyte, which comprises:a first storage means which stores a baseline detection starting time (tb1) and a baseline detection ending time (tb2) (wherein tb12) for determination of a baseline used for analysis of an analyte peak, a second storage means which stores a chromatogram of the analyte, a first arithmetic means which detects an analyte peak and its emergence time (tx, wherein tb12) on the chromatogram, and a second arithmetic means which detects a first baseline point between tb1 and tx by using a function having at least one of the level, the slope, the curvature and the gap from tx of the chromatogram at a particular point as the variables, detects a second baseline point between tx and tb2 by using a function having at least one of the level, the slope, the curvature and the gap from tx of the chromatogram at a particular point as the variables and gives a straight line passing through the first baseline point and the second baseline point as the baseline.
