摘　　要：气相色谱仪在天然气领域中发挥着重要作用,在长期的使用过程中,气相色谱仪硫化学发光检测器过高的H2/O2流速比会使其发生氢中毒现象。氢中毒会导致检测器的响应值大幅降低并影响到检测数据的准确度。本文通过对气相色谱仪的原理和双等离子体控制器的结构分析,并对双等离子体燃烧器陶瓷管进行高温活化处理,通过处理前后的实验数据对比,得出高温活化陶瓷管可在一定时间内解决双等离子燃烧器陶瓷管的氢中毒现象,此方法已在中亚管输天然气的离线检测中得到应用,并取得良好效果。GC plays an important role in the natural gas field,the long-term use,the hydrogen gas chromatograph poisoning sulfur chemiluminescence detector too high H2/ O2 flow rate ratio will make it happen.Hydrogen poisoning can cause response detector significantly reduced and affect the accuracy of test data.Based on the GC principles and dual plasma controller structural analysis,and dual plasma burner ceramic high temperature activation process,the experimental data before and after contrast,activation of high temperature ceramic tube can be obtained at a certain time resolved within hydrogen poisoning double plasma burner ceramic tube,this method was applied to off-line testing of the central Asian natural gas pipeline,and achieved good results.
