摘要
Abstract
It is the first time to establish a method of natural gas analysis by using isotope mass spectrometer（MAT271）.We tested the precision of MAT271,and the results showed that MAT271 is fit for nature gas composition analysis.The work compared the value of C2/C1 tested by MAT271 and chromatography,the error is not more than 0.01.And we also tested each pure composition of natural gas,summarized a set of quantitative calculation methods.By means of this method we tested the calibration gases.The relative standard of non-hydrocarbon is lower than 0.01%,and it is below 0.1% for hydrocarbon.The research compared the results with the standard values of the calibration gases.We summarized the advantages and disadvantages of this method.We hold that the method is suitable for dry gas composition analysis.关键词
