一种冷冻机油FVC68D中痕量氧化态杂质的荧光分析法

A ratio fluorescence method for determination of oxidized product in refrigeration oil FVC68D

基于氧化态冷冻机油FVC68D的荧光特性,以FVC68D冷冻机油为溶剂,建立了能够用于实际冷冻机油FVC68D中痕量氧化态杂质含量分析的比率荧光法。方法的定量范围是2~200 ppm(V/V),为冷冻机油质量控制贡献了新的方法。

Based on the fluorescent feature of oxidized refrigeration oil FVC68D,a ratio fluorescence method was proposed using refrigeration oil FVC68D as matrix for determining trace impurity resulted from unwanted oxidation.With a quantitation range of 2-200 ppm（V/V）,this reproducible and accurate method is expected to contribute to the quality control of refrigeration oil industry.
