## Abstract An enhanced surface coating method was developed for capillary electrophoresis (CE) using the natural polymer chitosan. The cationic property of chitosan at pH below 6.5 created a reversed electroosmotic flow (EOF) in the capillary. The EOF changed significantly with the run buffer pH a
## Abstract A new coated capillary has been introduced for capillary electrophoretic separation of anions by using a positively charged diazacrown ether with a 12βmembered ring. AΒ positive charge spread over the inner capillary surface led to a substantial anodic electroosmotic flow (EOF) over the
