摘要：

Coelectroosmotic capillary zone electrophoresis (CZE) has been investigated as a means of rapid analysis of twelve aromatic sulphonate compounds. The main factors affecting reversal of electroosmotic flow (EOF) type of osmotic modifier and concentration - were studied. Two types of osmotic modifier, an alkylammoniun salt (cetyltrimethylammonium bromide, CTAB) and a cationic polyelectrolyte (hexadimetrine bromide, HDB) were investigated. The composition of the running buffers was optimized according to the characteristics of each osmotic modifier. A concentration of HDB as low as 0.0001 % (w/v) was used successfully to provide a stable and reversed EOF.
