Evaluation of Poly S-179 as a stationary phase for the gas–liquid chromatography–mass-spectrometry of bile acid methyl ester acetates

Abstract

The stationary phase Poly S-179 has been found to offer distinct advantages over the previously reported SP-525 for the gas–liquid chromatographic separation of bile acid methyl ester acetates. Relative retention times of these bile acid derivatives are compared on the two phases.
