Abstract

The present invention provides a gas chromatography—inverse gas chromatography combined analysis device, which includes a gas chromatography column and an inverse gas chromatography column, an input end of the gas chromatography column is connected to a sample feeder, an output end of the gas chromatography column is connected to an input end of the inverse gas chromatography column, the output end of the gas chromatography column is further connected to a first detector, the input end of the inverse gas chromatography column is further connected to a carrier gas tube, an output end of the inverse gas chromatography column is connected to a second detector, and the first detector and the second detector are both connected to a signal collector. The present invention not only can investigate adsorption performance of a tested solid adsorption material with respect to a single probe, but also can investigate adsorption performance of different solid adsorption materials with respect to different constituents in a combined probe at the same time, thereby improving the development efficiency of the inverse gas chromatography technologies.
