Abstract Information :

Fatty Acid Methyl Esters (FAMEs) are a big threat in aviation fuels as well as in biofuels. Accurate quantitation and separation of cis-trans in the lower and higher boiling FAMEs is essential from a quality control perspective, as well as from a safety perspective. In this presentation a ZB-FAME GC column is utilized to accurately characterize FAMEs in Fuels by GC-MS.

Traditional selectivity, like a 100 % polyethylene glycol phase, may only have a few coelutions of FAMEs while the ZB-FAME GC column coupled with a mass spectrometry based detection will provide an excellent separation of cis and trans FAMEs along with lower level detection. Traditional higher cyano phase selectivities take an hour to separate cis-trans FAMEs, while the ZB-FAME can separate them within 11 minutes.This approach was also extended to a GCxGC using a ZB-FAME in the first dimension and a 5 % phenyl selectivity in the second dimension which together provide a detailed orthogonal separation. Thus an analysis of fuels by GCMS and GCxGC using ZB-FAME assures the safety in aviation fuels.
