Isotope Effects in Gas-liquid Chromatography of Steroids.

Gas and Liquid Chromatography

Gas-liquid chromatographic analysis of urinary steroids.

A method for gas-liquid chromatographic separation and quantitation of urinary steroid metabolites is described. A normal reference range has been established and classic examples of urinary steroid profiles of the major steroid disorders are given.

Identification and quantification of neutral fecal steroids by gas-liquid chromatography and mass spectrometry: studies

The excretion of fecal neutral steroids was studied in six normocholesterolemic subjects and one hypercholesterolemic subject fed a standardized diet supplemented with butter fat or corn oil. The neutral steroids in the diets and in feces were identified by gas-liquid chromatography combined with mass spectrometric analyses of the chromatographic effluents. The three main sterols in the diets w...

Wine: Gas and Liquid Chromatography

From the chemical point of view, wines are aqueous alcoholic solutions containing more than 1000 components that can be present at high concentrations (g L ), but also at trace levels (ng L ). Some of these components determine the organoleptic properties of wines, while others are signi"cant for classifying their origin and/or for checking whether some adulteration has taken place. Concentrati...
