Most of SF6 decomposition products are active, low in content and many kinds, so it is difficult to use one method for on-site quantitative detection. Some decomposes are very unstable and break down easily; Some of the decomposition is easily adsorbent, so the sample is collected into the sampling bottle, sent to the laboratory for analysis, the test results will reduce the concentration.
At present, the analysis methods of SF6 gas decomposition products are divided into laboratory detection and field detection according to the detection location. According to the detection principle, it is divided into detection tube method, gas chromatography, infrared spectrum method, Nuclear Magnetic Resonance spectroscopy (NMR) method, various combined analysis techniques and chromatography-mass spectrometry combined usage, chromatography-infrared combined usage, etc.
