    ISC'98 International Symposium on Chromatography. Rome, ITA, 1998/09/13.

    A sensitive capillary electrophoretic method was developed for the determination of thiodiglycolic acid (TDA) in urine which avoids the pretreatment of the urine sample.

    Several carrier electrolytes were examined.

    The most suitable carrier electrolyte system consisted of potassium hydrogen phthalate (5 mM), 2- (N-morpholino) ethanesulfonic acid (50 mM) and tetradecyltrimethylammonium bromide (0.5 mM), pH 5.2. Ten times diluted fresh midstream void urine was used for the determination.

    In this way, the concentrations of TDA between 5 and 50 mg/l in undiluted urine samples can be determined.
