摘要
研究了"冷凝富集—紫外分光光度法"测定发射场用气微量油含量时,标准物、气体取样流速和溶液静置时间对测定结果的影响。应用本文的研究结果,在特气中油含量分析时,可以在气体取样流速,溶液静置时间等过程上选择最优参数,提高气体分析化验的精度与效率。
The influence factors of trace oil content, containing standard material, rate of gas flow and solution stable time which were ob-tained by the method of “condensational enrichment - ultraviolet spectrophoto” to measure launching site gas was investigated. The optimal pa-rameters of flow velocity of sampling and standing time of the solution could be selected, which could improve the accuracy and efficiency of oil content analysis in special gas.
