| Abstract: | A procedure is reported to obtain reproducible and uniform inner walls of fusd-silica capillaries so as to benerate stable electrossmotic flow (EOF) in capillary zone electrophoresis (CZE), and strong polar compounds like nitrophenols are analyzed by CZE with such eapillaries in 2 minutes. By comparing three pretreatment methods of capillaries, it has been found that only the capillaries pretreated with base-containing methanol can produce constant EOF and contribute repeducible results. |
