摘要
Disclosed herein is a method for correcting an evolved gas analyzer and the evolved gas analyzer. The method includes: correcting a mass spectrum position to be located at a reference spectrum position, the mass spectrum position corresponding to a mass-to-charge ratio m/z of a mass spectrum of a gas component of a reference sample; calculating a sensitivity correction factor Cs=Ss/S by using an area S and a reference area Ss of a chromatogram, the sensitivity correction factor being used to measure an area of a chromatogram of the gas component of a test sample; and calculating a heating correction factor H=t/ts by using a time t and a reference time is indicating a maximum peak of the chromatogram about the reference sample, the heating correction factor being used to correct a heating rate of the test sample when measuring the gas component of the test sample.
