摘要
文章论述了应用气相色谱技术测定在用柴油机油中稀释柴油含量的方法,重点研究了进样量和柴油组分峰的积分时间对最终测试结果的影响。根据标准工作曲线回归系数R2值,最终确定进样量和积分时间的最佳值并加以讨论。对方法的重复性和再现性进行了考察,结果表明本方法精密度高,重复性不大于0.3%,再现性不大于1.6%,可满足设备维护和油品研究及使用中对在用柴油机油中稀释柴油含量测定的需要。
The test method for diesel fuel diluent in used diesel engine oils by gas chromatography was discussed. And the impact of injection volume and integration time of chromatography peak of diesel oil on the final result was emphatically studied. According to the regression coefficient R2 of standard working curve, the optimum values of injection volume and integration time were determined and discussed finally. The repeatability and reproducibility of the method were also examined. The results showed that the ...
