Usually determining micro-acetylene in liquified oxygen was very necessary in chemical production. The content of micro-acetylene in liquified oxygen used to be determined by colorimetric analysis, because the method was very complex and it's little colorimetric chromatism, chromatogram column to do chromatographic analysis was used. During many times contrast experiments, the results showed that the method had rapid analysis speed and high accruacy degree, the lowest examined concentration was 0.1×10 -6 .
