提高置换气各组分的分离度

Improve the Resolution of Each Component of the Replacement Gas

气相色谱置换气流路采用TCD检测器分析置换气中各组分(氢、氧、氮、甲烷、一氧化碳)的含量,为工艺检修置换分析提供准确数据。但在实际使用过程中发现各组分的分离度差,影响数据的准确及时报出。通过优化色谱的操作条件,更换色谱的定量管、色谱柱使之更好的分离,为生产提供准确及时的数据。

The gas chromatographic displacement gas flow path is analyzed by TCD detector to analyze the content of each component(hydrogen,oxygen,nitrogen,methane,carbon monoxide)in the replacement gas to provide accurate data for process overhaul analysis.However,in the actual use process,the separation degree of each component is found to be poor,and the data is accurately and timely reported.By optimizing the chromatographic operating conditions,the chromatographic tubes and columns are replaced for better separation,providing accurate and timely data for production.
