초록

항공유에 fatty acid methyl esters (FAME)가 혼합될 경우 연료 공급시스템과 항공기 엔진에 치명적인 고장의 원인이 될 수 있기 때문에 항공유 품질규격에서 FAME 함량을 50 mg/kg 이하로 규정하고 있다. 무수히 많은 탄화수소로 구성된 항공유 중의 FAME 성분을 선택적으로 분석하기 어렵기 때문에 본 연구에서는 MDGC-MS를 사용한 새로운 시험방법을 개발하였다. Deans switching 시스템이 설치된 MDGC-MS를 이용하면 코코넛 오일이나 팜유 유래의 저분자량 FAME 성분도 분석이 가능함을 확인하였다. 개발된 시험방법은 FAME 피크의 머무름 시간을 약간 뒤로 이동시키는 매질 효과(matrix effect)를 현행의 기준 시험방법(IP 585)보다 약 20배 이하로 감소시킬 수 있었다. MDGC-MS는 항공유에 미량의 FAME가 오염되었는지 여부를 정성 및 정량적으로 확인할 수 있는 시험방법으로 적합하였다.

The current allowable cross-contamination level of fatty acid methyl esters (FAME) in aviation turbine fuel (AVTUR) is 50 mg/kg, due to that the presence of FAME in AVTUR can significantly impact the fuel supply system and jet engine. It has been difficult to analyze the level of FAME in AVTUR, since it is consisted of a lot of hydrocarbons. In this study, thus, a new method using multi-dimensional GC-MS (MDGC-MS) was proposed in order to determine the FAME level in AVTUR effectively. Applying to MDGC-MS with Deans switching system enabled us to detect and quantify the FAME with low carbon numbers such as those derived from coconut oil and palm kernel oil. The matrix effect of MDGC-MS method, which could shift the FAME peaks to slightly longer retention times, was reduced by 20 times compared with that of 1-dimensional GC-MS reference method. This developed method could be suitable for qualitative and quantitative analyses to determine the contamination level of trace FAME in AVTUR.
