提高氩气中杂质的检测质量

根据气相色谱分析的工作原理，运用DHP-05型氩气纯度分析仪对空分设备提取氩中的杂质气体-H2、O2、N2、CH4、CO、CO2进行全分析，通过对多年的氩气分析实践经验进行总结，阐述了气流波动、有机物变化、极化电压等各因素对氩气纯度分析的影响情况，并针对各因素的性质和特点，分别采取相应的措施进行调整和处理，从而找到氩气纯度分析的最佳工作条件，对仪器的一些不足之处进行了相应的改进，提高了氩气分析的准确性、重复性和及时性。

Based on the working principles of gas chromatograph, DHP - 05 type argon purity analyzer is applied to take overall analysis on the impurity gases of H2 、 O2 、 N2、 CH4、 CO、 CO2 in the argon gas generated in air separator. Through the summarization of the experience of several years＇argon analysis practice, the paper elaborates the effects of various elements such as gas flow fluctuation, organic matter changing, polarization voltage on argon gas purity analyzer. In light of the properties and characteristics of each element, corresponding measures are adopted to adjust and handle, thus the optimistic operation conditions for argon purity analysis are found out. And corresponding improvements are carried out aiming at some shortcomings of the analyzer, raising the accuracy, repeating and prompt of argon analysis.
