New Method Determines FAME in Aviation Turbine Fuel by Gas Chromatography

PAC是全球领先的实验室和在线工艺应用先进分析仪器供应商,率先推出了IP 599方法,“航空涡轮燃料中脂肪酸甲酯(FAME)的测定 - 使用中心切割和重新聚焦的气相色谱”,最近由能源研究所(EI)批准并出版。 作为批准过程的一部分,EI进行了深入的实验室间研究,其中包括来自欧洲和加拿大的8实验室通过该方法分析样品。 能源研究所计算的精度超过了IP 583(IR),IP 585(GC-MS)和IP 590(HPLC)等竞争技术的已知陈述。

PAC developed this new method after its AC FAME in AVTUR analyzer, a unique gas chromatography analyzer combining deans-switching and re-focusing. It provides accurate quantitative data on individual and Total FAME components in the range of C16 to C18 with the option to analyze C14 FAME which is a marker for the presence of lower chain methyl esters such as those produced from coconut oil. This innovative method is specified for the range of approximately 3.5 to 116 mg /kg FAME; this is sufficient to meet the 5 mg/kg lower limit defined in DEF STAN 91-91 and ASTM D1655.

“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.”
