## Abstract Separation of inorganic anions by capillary electrophoresis (CE) is usually conducted in coβelectroosmotic mode due to the large electrophoretic mobilities of inorganic anions. Semipermanent surfactant coatings have been shown to be effective for CE of inorganic anions due to their stro
## Abstract This paper proposes a new method for CE separation of inorganic anions based on the use of gemini surfactants as capillary coatings in mixed aqueousβorganic solvents. The semipermanent gemini surfactant coatings were facilely prepared by rinsing the capillary with 18β__s__β18 solutions;
An electrophoretic method for the simultaneous separation and determination of cationic and anionic surfactants based on double electrokinetic injection from the two ends of the capillary is proposed here. Nonaqueous capillary electrophoresis (NACE) with methanol as solvent was used to reduce the el
## 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
