Abstract

국산휘발유중의 탄화수소를 45 m squalane SUS WCOT 모세관 컬럼을 사용하여 기체크로마토그래피-질량분석계로 분석한 결과, 크로마토그램피크 약 59개를 분리·정량하였고 그중 31개 피크를 정성확인하였다.
탄화수소 성분은 휘발유의 종류와 관계없이 크로마토그램 패턴이 상호유사하며, 단지 고급이 보통 휘발유에 비해 방향족 탄화수소 함량이 많다. 이것은 휘발유 조합공정의 차이에 기인한다고 본다.

A combined system of a capillary gas chromatography and mass spectrometer permits rapid analysis of gasoline.
The analysis is conducted on a 45 m squalane SUS WCOT capillary column in less than 30 min.
Chromatographic peak identifications and detailed quantitative composition of premium and regular domestic gasolines are presented.
All gasolines have similar constitutions which are found to contain essentially the same hydrocarbons, differing only in concentration.
Premium gasolines have greater percentages of aromatic hydrocarbons than regular gasolines because of the difference in blending schemes.
