| Abstract: | The gas flow path of HP-4890D gas chromatograph was modified by adding a 10-way switch valve for analyzing micro-amount CO and CO_2 in polymer grade propylene. The pollution of large amount of propylene is eliminated by bachflush with two-column system. The method is rapid and ac- curate. |
