Abstract
We report on 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. The kinetics of adsorption and desorption of catecholamines from plasma on to alumina has been studied using laboratory-prepared and some commercial aluminas with various acids. Chromatographic conditions yielding optimal resolution and sensitivity have been characterised. Some possible interfering peaks have been identified. The stability of catecholamines in plasma has been studied.
