气相色谱法测定汽油中C_1～C_4烃类含量

Determination of C_1～C_4 Hydrocarbons in Gasolines by Chromatography

本方法用于催化裂化汽油及其它汽油中所含气体烃类的分析．以石墨化炭黑作柱填料，密封管采样，用归一化法进行定量，简化了操作，提高了方法的准确度和精密度．

The method is used to determine the contents by the area normalization of C1~C4hydrocarbons in gasolines.using graphitized carbon black as colunm packing and introducing sample underpressure.It overcomes the shortcomings of the internal standard method and accuracy and precision are improved obviously.
