气相色谱法测定液氧中乙炔含量的试验研究

摘要

The space division workshop of oxygen generation plant in a company adopts gas chromatographic method to determine the content of acetylene in liquid oxygen instead of the original visual colorimetric method, and through the comparison of the experimental data, the accuracy of gas chromatographic method analysis is raised substantially, which guarantees safety in production.%　　某公司制氧厂空分车间原来采用目视比色法测定液氧中乙炔的含量，存在工艺复杂，消耗试剂多，误差大等缺点。采用气相色谱法代替原来的目视比色法，经试验数据对比，气相色谱法分析准确度大幅度提高，有效的保障了安全生产。
