Abstract
We tested different column temperatures and carrier gas linear velocities in a capillary GC system with a highβresolution column, DBβ23, to determine the shortest run time for analyzing the major components of a fatty acid methyl ester sample from any lipid source. Depending on the sample, the run time is 2 min or less. Commerciallyβavailable highβresolution columns can be used without modification.

## Abstract An injection splitter in front of a glass capillary column was used for the hydrogenation of fatty acid methyl esters (FAME) mixtures. Hydrogenation followed by gas chromatographic analysis on capillary columns permitted detection and identification in complicated natural mixtures of br
A method was developed to analyze and quantitate volatile fatty acids such as acetic, propionic, butyric, iso-butyric, valeric, and iso-valeric acid from samples of biological origin. A capillary column system including an automatic on-column injection device as well as a precolumn of larger interna
