[Methodology in the study of organic acids in children].
A method is described for the extraction of urinary organic acids in children, their conversion to TMS and oxime TMS derivatives and their separation by gas liquid chromatography on a packed column of 10% OV 101. The compounds are identified by mass spectrometry. Profiles of urinary organic acids in normal neonates and in several metabolic disorders are presented.
