Abstract

The invention relates to the technical field of gas detection, in particular to a method for detecting the concentration of specific gas in an explosion dangerous place, which comprises the following steps: sampling by using solid-phase microextraction on site, and carrying out off-line detection on the collected sample by using a surface acoustic wave gas chromatograph. And calculating and analyzing according to the detection result to obtain the concentration of the target component gas in the explosion dangerous place, and finally realizing the rapid detection of the concentration of the specific gas in the explosion dangerous place. According to the method for analyzing the concentration of the specific gas in the explosion dangerous place through SPME coupled GC-SAW detection, the sample collected by SPME does not need to be pretreated and can be directly injected and detected, the sampling and detection methods are safe, and the whole detection time period is greatly shortened.
