Portable natural gas odorant analysis gas chromatograph

The utility model discloses a portable natural gas odorant analysis gas chromatograph which is characterized by comprising a carrier gas cylinder, a carrier gas purifier, a ten-way membrane valve, a column oven, a chromatographic column, a quantitative loop, a battery pack, an EPD detector, an electromagnetic valve, a main board and a sampling pump. According to the portable gas chromatography platform, the EPD detector is integrated to the portable gas chromatography platform, so that the advantages of the EPD detector and the portable gas chromatography can be played at the same time, and the problems of a traditional sensor detection method and a gas chromatograph are solved. The method has the advantages of small size, light weight, high sensitivity, high selectivity and the like, and has a wide application prospect. According to the utility model, the problems of poor separation, low sensitivity, susceptibility to interference and inaccurate quantification of a common sensor detection method can be solve
