研究了氧化锡为主体的N型气敏半导体作为气相色谱鉴测器的基本性能,其灵敏度与氢火焰鉴测器相当,一般物质可测至1~10 ppm,氢测到0.1ppm.试制成功了由此鉴测器构成的QSP-1型气敏色谱仪,经对稀有气体中微量氢杂质、电力变压器油气和某工厂乙烯车间大气污染等进行的分析,以及对石油勘探油气层位的测定等方面的应用研究,表明仪器灵敏度高、结构简单,可在某些实际中应用. The basic properties of N-type gas sensing semiconductors with tin oxide as gas chromatographic detector are studied. The sensitivity is about the same as that of hydrogen flame detector. The general properties are as follows: 1 ~ 10 ppm for general substances and 0.1 ppm for hydrogen. Based on this detector QSP-1 gas chromatograph, analysis of trace hydrogen impurities in rare gases, power transformer oil and air pollution in a factory ethylene plant, as well as the determination of oil and gas reservoirs in oil exploration And other aspects of applied research, indicating that high sensitivity instruments, simple structure, can be used in some practical.
