Analysis of total urinary catecholamines by liquid chromatography: methodology, routine experience and clinical interpretations of results [PDF]

open access: yes, 1983
A simple routine method is described for simultaneous assay of total urinary adrenaline, noradrenaline and dopamine. The catecholamines are pre-purified on a small ion-exchange column, separated by reversed phase ion-pair liquid chromatography, and are ...

ION EXCHANGE CHROMATOGRAPHY

open access: yes, 2023
Ion exchange chromatography is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. Ion exchange chromatography is probably the most powerful and classic type of liquid chromatography. It can also used for almost all kinds of charged molecule including large proteins, small nucleotides and amino
