瓦斯样品中气体成分分析

ANALYSIS OF COALBED GAS COMPOSITION IN GAS SAMPLE

将野外装入解吸罐中的煤芯样,用真空脱气装置脱气,脱出的气体通过GC4008B气相色谱仪进行组份浓度测定,记录的数据经A5000气相色谱工作站数据处理软件处理。从而快速、准确地测定出CO、CO2、CH4、C2H4、C2H6、C3H8以及重烃等气体成分的含量。用于大批量实际样品测定,符合质量管理的要求。

Put coal core sample in analysis tank in the field and degassed it in a vacuum degasser.The gas product was determined for its compositional concentration with gas chromatograph GC4008 B.Recorded data was processed with A5000 gas chromatograph workstation data processing software.It was fast to measure the contents of CO,CO_2,CH_4,C_2H_4,C_2H_6,C_3H_8 and heavy hydrocarbon gases.It meets the quality requirement when used for measurement of samples in large quantities.
