五阀七柱气相色谱法快速测定进口天然气的组分
Rapid Determination of Components of Imported Natural Gas by GC with Seven Columns and Five Valves
摘 要
利用气相色谱仪,通过5个转动阀,7根色谱柱和3个检测器,建立了五阀七柱气相色谱分析系统,实现了进口天然气中多种组分的同时测定。方法用于天然气标准物质和样品的分析,分析天然气标准样品的测定结果与认定值相比,误差在-0.015%~0.020%之间,样品测定结果的相对标准偏差(n=5)在0.020%~22%之间。

Abstract
A gas chromatographic system with 7 columns, 5 valves and 3 detectors was established, and it was applied to the simultaneous ultimate and determination of determine components of imported natural gas. The proposed method was applied to the analysis of standard sample and substantial samples of natural gas. In the analysis of a standard sample of natural gas, relative errors ranged from -0.015% to 0.020% as referring to the certified values, were obtained. Values of RSD′s (n=5) found from the results of analysis of substantial samples were in the range of 0.020% to 22%.
