Gas-solid chromatographic confirmation of vinyl chloride levels in oils and vinegars by using electrolytic conductivity detection. 1977

B D Page, and R O'Grady

A gas-solid chromatographic headspace method has been developed for the quantitative confirmation of vinyl chloride (VC) in oils, and vinegars. The method, based on the electrolytic conductivity detector, permits quantitative confirmation of VC residues as low 0.05 and 0.02 ppm for oil and vinegar, respectively. A number of samples were analyzed by using a previously reported flame ionization method and the proposed technique. The results by using the latter technique averaged 5% lower.

UI	MeSH Term	Description	Entries
D009821	Oils	Unctuous combustible substances that are liquid or easily liquefiable on warming, and are soluble in ether but insoluble in water. Such substances, depending on their origin, are classified as animal, mineral, or vegetable oils. Depending on their behavior on heating, they are volatile or fixed. (Dorland, 28th ed)
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
