新方法通过气相色谱法确定航空涡轮燃料中的FAME

PAC, a leading global provider of advanced analytical instruments for laboratories and online process applications, pioneered the IP 599 method, “Determination of Fatty Acid Methyl Esters (FAME) in aviation turbine fuel – Gas Chromatography using heart-cut and refocusing”, that was recently approved and published by the Energy Institute (EI). As part of the approval process, EI conducted an in-depth interlaboratory study that included 8 laboratories from Europe and Canada analyzing the samples via this method. The precision, as calculated by the Energy Institute, exceeds the known statements for competing technologies such as IP 583 (IR), IP 585 (GC-MS) and IP 590 (HPLC) methods.

PAC在AVTUR分析仪中使用AC FAME开发了这种新方法,AVTUR分析仪是一种结合了转换和重新聚焦的独特气相色谱分析仪。 它提供了C16至C18范围内单个和总FAME组分的准确定量数据,并可选择分析C14 FAME,它是存在低级链甲酯(如椰子油生产的甲酯)的标记。 这种创新方法规定的范围约为3.5至116 mg / kg FAME; 这足以满足DEF STAN 5-91和ASTM D91中定义的1655 mg / kg下限。

“In addition to higher precision and analyzing a wide range of jet fuels, this new method utilized by the AC FAME in AVTUR instrument is the easiest one to perform due to no sample preparation or complex multi component calibrations,” says David Tran, Vice-President of PAC Product Management and Marketing. “Due to its ease of use, a highly educated chemist is no longer required to run this analysis. It can now be used for routine analysis by refineries, distribution and pipeline companies, independent labs, airline companies, or military for the measurement of FAME (biodiesel) in jet fuel.”
