Abstract
A systematic investigation into some frequently encountered problems in the estimation of catecholamines in plasma and biological fluids using high-performance liquid chromatography with electrochemical detection is reported on. The kinetics of adsorption and desorption of catecholamines from plasma on to alumina was studied using laboratory-prepared and some commercial aluminas with various acids. Chromatographic conditions yielding optimal resolution and sensitivity were characterized. Some possible interfering peaks were identified. The stability of catecholamines in plasma was studied.This publication has 31 references indexed in Scilit:
