PROBLEM TO BE SOLVED: To form a calibration curve of higher precision without relying on the experience or skill of an analyst. SOLUTION: A standard sample for calibration containing a plurality of sample components known in molecular weight is subjected to GPC analysis to collect data and the peaks appearing in a formed chromatogram are detected. If the holding times of the peak tops of the respective peaks are decided, the relation between the molecular weights and the holding times is held to a calibration point table (S11-S15). (M) calibration points are selected from this table (S16) while the calibration points are adapted to a plurality of prepared approximation formulae to calculate a coefficient and the respective approximation formulae are determined to calculate approximation errors (S17 and S18). After the respective approximation formulae are determined by variously changing the selective combinations of the calibration points, a list wherein the approximation formulae are arranged in the smaller order of the approximation errors is displayed as a calibration curve candidate (S21 and S22). The analyst selects the calibration curve from the list. COPYRIGHT: (C)2007,JPO&INPIT
