Abstract
PURPOSE: To exclude the effect due to variation of atmospheric pressure simply, by comparing the measuring value of reference gas with the reference value obtained in advance, obtaining the ratio and multiplying this rate with the amount of content in the process gas obtained with the measurement.
CONSTITUTION: The sampling valve 2 given with the process gas and the sampling valve 1 given with the reference gas known in the concentration are provided and the sampling valves 1, 2 are operated within one analysis period. The measuring value of reference gas obtained with the column 3 and the detector 4 is compared with the reference value obtained in advance, the rates are obtained, and the effect due to the variance of atmospheric pressure is excluded by multiplying this rate with the amount of content in the process gas obtained from this measurement.
