气相色谱仪检定装置的使用方法

摘要

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.%依据JJG 700-1999《气相色谱仪检定规程》介绍气相色谱仪检定装置的使用方法.检定项目包括载气流速稳定性、柱箱温度稳定性和程序升温重复性、衰减器换挡误差以及检测器的灵敏度.给出了热导检测器(TCD)、火焰离子化检测器(FID)、火焰光度检测器(FPD)、电子俘获检测器(ECD)和氮磷检测器(NPD)检定时的色谱条件及使用注意事项.正确使用气相色谱仪检定装置能保证仪器测量数据的准确可靠.
