用天然气气相色谱分析仪快速分析天然气组分及性能参数

介绍用天然气气相色谱分析仪分析天然气中无机组分、有机组分和热值的方法,确定了分析方法和条件,该方法测量结果的相对标准偏差小于1%。采用该方法对制备的标准气体进行了考察,并将该方法用于天然气气体标准物质的性能评价和国际实验室间的比对,天然气组分含量比对相对误差在±1%之内,热量值比对相对误差在±3%之内,取得了国际等效性。

ANALYZING NATURAL GAS COMPOUNDS AND CAPABILITY PARAMETERS QUICKLY BY NATURAL GAS GC

A method for analyzing organic compounds and inorganic compounds in natural gas and thermal amount quickly by natural gas GC was introduced.The GC method conditions were presented.The relative standard deviation of determination results was less than 1%.The method was used for determination the calibration gases.International equivalent effect was acquired by evaluating the capability of natural gas calibration gases and comparing experiments results.The comparison error of components was within 1% and comparison error of thermo amount was within 3%.International equivalence was obtained.
