利用加入反吹系统的2307型气相色谱仪分析聚合级丙烯中微量CO、CO2含量

Analysis of Micro-amount CO and CO 2 in Polymer Grade Propylene by Modified SP-2307 Gas Chromatograph

通过对２３０７型气相色谱仪的气路改装，实现了对丙烯中微量ＣＯ、ＣＯ２含量的快速分析。同时以氢气为载气，提高了分析的灵敏度，结果令人满意。

In the paper it have been expounded that the gas flow path of sp-2307 gas chromatograph was modified by adding a 6-way switch valve for analyzing micro-amount CO and CO 2 in polymer grade propylene. The method is rapid, sensitive and with satisfactory results.
