Abstract

PURPOSE:To accurately measure a peak area of a gas chromatograph, by setting a peak height detection interval and an integral interval of a peak area of the gas chromatograph separatey. CONSTITUTION:A peak height of a peak component is detected at every detection interval delta1 in accordance with the minimum component width of a chromatograph and the integral addition processing is carried out by an integral interval delta2 separately set from the interval delta1 which is selected in accordance with the peak component width by an adder 11 through an A/D converter 1. This interval delta2 is selected most suitably so as to be delta2=3delta1 in accordance with a width ratio 3 of the minimum peak component and peak component. On the other hand, a gate width T corresponding to the peak component is determined by a timer 3 and a gate set device 4 and the adder 11 is controlled through an integration beginning detector 7 and an end point detector 8 and then, the integral value of <=100 base line is substrated by memory devices 9, 10 and an operator 12. The integral area is determined accurately without effected by the noise, etc. by a system setting this integral area in accordance with a variation rate corresponding to the peak component width separately from the peak value detection interval.
