## 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 aqueous‐organic solvents. The semipermanent gemini surfactant coatings were facilely prepared by rinsing the capillary with 18‐__s__‐18 solutions;

## Abstract As an alternative to acid pretreated UCON and FFAP capillaries for the analysis of wide‐boiling free fatty acid mixtures, OV‐1 : FFAP phase mixtures were used on high‐temperature silylated inert glass capillary columns. The HETP‐carrier gas velocity curves, peak asymmetry factors, coati
For the preparation of capillary columns by the static coating method [I] considerable volumes of solution containing the liquid phase in a concentration range of 0.05-2.0% are used. For convenience and economy we have for many years prepared such solutions in batches of 50-100 ml, and have continue
