Gas-liquid chromatographic determination of tienilic acid (SKF 62.698) in human plasma and urine. 1976

J P Desager, and M Vanderbist

A gas-liquid chromatographic method is described for the determination of tienilic acid (SKF 62.698), a diuretic with uricosuric properties, in human plasma and urine. The method, which is based on the methylation of the compound, is rapid, specific and sensitive. The lowest level accurately determined is about 50 ng/ml in plasma and 1 mug/ml in urine. The first results from a human volunteer are given.

D010642	Phenoxyacetates	Derivatives of phenoxyacetic acid, including its salts and esters.
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.
