[Urinary excretion of 17-ketosteroids studied by gas chromatography in the healthy adult: distribution of values]. 1976

B Van de Walle, and J P Dessaint, and A Racadot

The level of different urinary 17-ketosteroids were assayed using a method requiring an enzymatic hydrolysis and a solvolysis, a separation by gas-chromatography on OV 225 (cyanopropylsilicone) and a detection by flame ionisation. The method has been discuted. Statistical study of the results obtained in 89 healthy and ambulatory subjects (divided in 4 groups according to sex and age) has shown a log-normal distribution of urinary excretions.

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.
