The utility model discloses an integrated full -automatic headspace sample
injector and gas chromatograph combined device, including headspace sample
injector, valve box, transmission
pipe and
gas chromatography unit, the valve box is located in the high temperature area of
gas chromatography unit one end sample
injection port vicinity, the sample
injection port of
gas chromatography unit is connected with valve box
through transmission pipe, the utility model discloses a headspace sample
injector valve box split design, and the headspace sample injector valve box is placed in the high temperature area of the sample
injection port vicinity of the matched gas
chromatography unit, and the valve box independent
heating temperature control is favorable to the rapid heating and heat preservation of valve box, is favorable to the saving of
electric energy, shortens the transmission
pipe length between headspace sample injector and the sample injection port of gas
chromatography unit, improves chromatographic peak shape, and improves analysis result accuracy, and transmission pipe is small and subtle, and the appearance of headspace sample injector and gas chromatograph matched combination is harmonious and beautiful.
