摘要
建立了气相色谱同时测定氧气、氮气、一氧化碳、甲烷、二氧化碳、乙烯、乙烷、丙烷、丁烷的方法。目标分析物经常温、加热、破碎提取后,在气相色谱仪(HP6890)采用色谱柱AT C-2000(中科院兰州物理化学研究所,规格为25 m×0.53 mm×0.25μm)进行检测。所得相关系数(r)均大于0.99;检出限的体积百分比均小于0.08%。该方法满足了煤层气中各成分检测的需要。
Build gas chromatographic simultaneous determination of oxygen,nitrogen,carbon monoxide,carbon dioxide,methane,ethylene,ethane,propane,butane method.Target analyte often temperature,heating,broken after extraction,in gas chromatography(HP6890) the chromatographic column AT C-2000(Chinese academy of sciences,lanzhou institute of physical chemistry specification of 25 m x 0.53 mm x 0.25 um) is the test.The correlation coefficient(r) were greater than 0.99;Detection limit volume percentage were less than 0.08 %;This method meets the CBM ingredients in the detection of the need.
