✦ Synopsis

The effects of repeated cross-linking of SE-54 stationary phase with azo-tert.butane on the degree of stationary phase film immobilization and on the chromatographic properties were studied. The optimum numbers of repeated immobilizations in the columns for gas and liquid chromatography were determined. Excessive repetition of immobilization adversely affected the chromatographic properties. The contribution of chemical bonding to the degree of stationary phase immobilization was studied with capillaries silylated with octamethylcyclotetrasiloxane.

A method for preparation of capillary columns and traps with a very thick film (up to 100 pm) of stationary phase is described. The principle of this method is based on an immediate fixation of a film of prepolymer, formed during dynamic coating. Thus, the development of film irregularities, such as

## Abstract The influence of different polysiloxane solvents on the efficiency and stereoselectivity of columns coated with mixtures of heptakis(2,3‐di‐O‐methyl‐6‐O‐__tert__‐butyldimethylsilyl)‐β‐cyclodextrin (DIME‐6‐TBDMS‐β‐CD) and the polysiloxanes was investigated. In the case of DIME‐6‐TBDMS‐β‐
