GAS CHROMATOGRAPH SYSTEM AND VOC MEASURING APPARATUS USING IT

摘要

PROBLEM TO BE SOLVED: To provide a gas chromatograph system capable of easy calibration work and a VOC-measuring apparatus.;SOLUTION: The gas chromatograph system is provided with both a detector 30 comprising a semiconductor sensor provided for the exhaust side of a gas separation column and an arithmetic processing unit 33. In calibration mode, the arithmetic processing unit 33 determines a calibration calculation formula for correcting output, in such a way that the concentration of gas of gaseous components to be detected, determined on the basis of peaks of output of the detector 30 matches the concentration of gas of a gas for calibration inputted through the use of an input part 38. In detection mode, the arithmetic processing unit 33 corrects the peaks of output of the detector 30 on all the gas components to be detected, through the use of the calibration calculation formula and determines the concentration of gas, corresponding to detection output after correction on the basis of calibration curve data stored to a memory 33a.;COPYRIGHT: (C)2006,JPO&NCIPI
