title: Gas chromatographic/mass spectrometric identification of 3-hydroxydicarboxylic acids in urine.
abstract: Organic acid profiles were routinely analysed for two patients suffering from a massive 3-hydroxydicarboxyluria and five patients suffering from ketoaciduria. The identification of the urinary, saturated and unsaturated 3-hydroxydicarboxylic acids as their trimethylsilyl derivatives was performed with electron impact and positive chemical ionization gas chromatography/mass spectrometry. Additionally, their methylene units have been determined on SE-52 and OV-1701 types of stationary phases.
