New GC Column Technology for Old Problems in Fatty Acid Analysis

Food testing regulatory methods around the world require separation of fatty acid and its isomers when determining fatty acid composition by GC/FID. This is, perhaps, one of the oldest and most popular gas chromatography analyses. While many other GC methods have adopted new trends such as shorter, high-efficiency GC columns, or moved to more selective detectors, such as mass spectrometers, the GC/FID method for analysis of free fatty acids or cis-trans fatty acids isomers has seen little change in the last few decades. This is in part because the set of analytes that needs to be resolved is challenging.
