摘要：

A selective on-line sample concentration technique of anion selective exhaustive injection (ASEI)-sweep-micellar electrokinetic chromatography (MEKC) was evaluated using a cationic surfactant. To suppress the electroosmotic flow, a polyacrylamide-coated capillary was introduced. Some aromatic carboxylic acids, dansyl amino acids, and naphthalene-disulfonic acids were used as test analytes. About 1000- to 6000-fold increases in detection sensitivity were obtained in terms of peak heights by ASEI-sweep-MEKC. (C) 2001 Elsevier Science B.V. All rights reserved.
