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