摘要
Abstract
The method for separation and determination of sulfur compounds in natural gas was established by applying gas chromatography with pulsed-flame photometric detector. The effects of separation condition were discussed. Inert silanized sample injection system was used to inject. Qualitative and quantitative research of sulfur compounds in natural gas was established by using the retention time of the standard material and the external standard method. The experimental results indicated that determination of sulfur compounds in natural gas by applying gas chromatography with pulsed-flame photometric detector can simplify operation procedures and shorten analysis time, besides the repeatability of this method was very good. Five repeatable determinations of the same sample showed that the relative standard deviations of the sulfur compounds were less than 5% , and the recovery of the method was between 98.6% and 101.2 %. Accuracy of the method can meet analytical requirements.关键词
