Abstract

In order to improve the resolution of catecholamines, the control of both the electroosmotic and the electrophoretic mobilites were carried out. The former was controlled by the addition of borate ion and a change in pH. The control of the latter was carried out by addition of a cationic surfactant. Ten catecholamines were sufficiently separated.
