Abstract

The isotachophoretic separation of catecholamines based on inclusion complex formation with β-cyclodextrin (β-CD) was investigated. Separability was improved with increasing concentration of β-CD in the leading electrolyte. It was found that a neutral surfactant, added to suppress the electroosmotic flow and to form sharp zone boundaries, affects the resolution. Six catecholamines were separated by using complex formation with β-CD.
