喷气燃料中芳烃总量的测定方法优化

Optimization of determination method for total aromatics in jet fuel

采用现有分析方法以ASTM D6379示差折光检测器高效液相色谱法为依据,开发气相色谱法接入芳烃捕集阱和脱氧装置测定喷气燃料中总芳烃含量的测定方法。采用该方法考察了多个喷气燃料样品和质控样测定总芳烃含量,通过加入标准物质考察该方法对喷气燃料加标回收率为97.16%~105.88%,标准偏差小于0.5%。因此认为气相色谱法适用于喷气燃料中芳烃总量的测定。

Using the existing analytical method and based on SATM6379 differential refractive detector high performance liquid chromatography a method for determining the content of content of total aromatics in jet fuel by gas chromatography connected to aromatics trap and deoxidation device is developed.Through adding reference materials,the recovery rate of jet fuel was97.16%-105.88%.The standard deviation was less than 0.5%.Therefore,the gas chromatography method was considered to be suitable for the determination of total aromatics in jet fuel.
