Development and Performance Verification of a Portable Gas Automatic Sampling Device
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.
