See Jonathan Smuts, Applications Scientist, Present on “Trans-fat Determination by Gas Chromatography Vacuum Ultraviolet Detection”

Vacuum ultraviolet detection for gas chromatography (GC-VUV) has been applied to the analysis of fatty acid methyl esters (FAME). Here we specifically apply the technology for the quantitative determination of trans-fat in various food samples. Two GC columns are explored, 100% cyanopropyl and a PEG-based column. Linearity is demonstrated and then used to calculate relative response factors. These are then applied to a variety of food samples: fish oil, biscuit, baby formula, gummy vitamin and butter. Finally, quantitative GC/VUV results are compared to GC/FID.
