一种便携式气体自动进样装置的研制及性能验证

Development and Performance Verification of a Portable Gas Automatic Sampling Device

根据JJG 700-2016《气相色谱仪检定规程》对火焰离子化检测器(FID)和热导检测器(TCD)的检校要求,设计并研制一种便携式气体自动进样装置。该装置可实施气体的连续自动进样,进样体积范围覆盖(0.1~5.0)mL,且性能验证实验测得的连续7次峰面积重复性(RSD)为0.9%。同时,装置自身的稳定性和操作的便利性,能有效提高气相色谱仪的计量质量和效率。

According to the calibration requirements of flame ionization detector(FID) and thermal conductivity detector(TCD) in JJG 700-2016 "Verification Regulations for Gas Chromatographs", a portable automatic gas sampling device is designed and developed.The device can perform continuous automatic gas injection in a volume range of(0.1~5.0)mL, and the seven consecutive peak area repeatability(RSD) measured by the performance verification experiment is 0.9%.At the same time, the stability of the device itself and the convenience of operation can effectively improve the measurement quality and efficiency of the gas chromatograph.
