摘　　要：介绍武钢氧气公司氢火焰气相色谱仪利用Al2O3柱测定空分设备液氧中乙炔含量的方法。通过PQ柱和Al2O3柱的比较、检测器的对比和对样品气的测定试验,确定采用Al2O3柱对空分设备主冷液氧中乙炔杂质含量的检测方法的准确性和可靠性。阐述试验条件和测定结果。Here, one method is briefed to measure acetylene content in liquefied oxygen of liquefied oxygen in air separation plant with Al2O3 column of hydrogen flame gas chromatograph of this oxygen company. Through comparison of PQ column and Al2O3 column, comparison of detectors, and test of sample gas, the correctness and reliability of the method with Al2O3 column to detect the content of acetylene impurity in liquefied oxygen of main condenser of air separation plant are accepted. The test condition and measurement results are corffirmed.
