| Abstract: | According to JJG 700-1999 Verification Regulation of Gas Chromatograph,the method of using gas chromatograph verification device was introduced.The test items included the carrier gas flow rate stability,cylinder temperature stability,programmed temperature repeatability,attenuator shift error and the sensitivity of the detector.The chromatographic conditions and matters needing attention during the verification of thermal conductivity detector(TCD),flame ionization detector (FID),flame photometric detector(FPD),electron capture detector(ECD),and nitrogen phosphorus detector(NPD) were given.The correct use of gas chromatograph verification device can ensure the accuracy and reliability of the instrument measurement data. |
