On-line coupling of reversed-phase liquid chromatography and gas capillary chromatography (RPLC-GC) using a programmed temperature vaporizer (PTV) as interface is used for the direct and simultaneous analysis of free sterols, tocopherols, and squalene of edible oils by direct injection (that is, wit...
