Sample preparation with ion-exchange resin before liquid-chromatographic determination of plasma catecholamines.
Estimation of plasma catecholamine concentrations by "high-performance" liquid chromatography, although increasingly used, still presents difficulties. We describe a method for clean-up of plasma samples on cation-exchange resin before they are extracted with alumina. This procedure elimin...
