  • Title: Gas chromatographic/mass spectrometric identification of 3-hydroxydicarboxylic acids in urine.
    Author: Verhaeghe BJ, Van Bocxlaer JF, De Leenheer AP.
    Journal: Biol Mass Spectrom; 1992 Jan; 21(1):27-32. PubMed ID: 1591279.
    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.
