title: [Quantitative determination of the o-phthaldialdehyde derivatives of noradrenaline, dopamine and normetadrenaline in urine with an amino acid analyzer (author's transl)].
abstract: Noradrenaline, dopamine and normetadrenaline in urine are separated by a cation-exchange resin (DC 6A, Durrum) and a commercially available amino acid analyzer. After separation, the o-phthalaldehyde derivatives of the compounds are formed by the usual pumping system and are quantified with a fluorimeter. Pre-packed ion-exchange columns (Bio-Rad, Munich) are used for purification and fractionation of the urine samples.
