✦ Synopsis

A new simplified method was developed for the preparation of immobilized stationary phase fused silica capillary columns coated with OV-1-vinyl, SE-54, and OV-1701 -vinyl. This methodology includes the application of the moderately polar stationary phase OV-1701 -vinyl as a surface deactivation agent that may also participate in the dicumyl peroxide initiated free radical immobilization process. Practical details of the procedure are presented and applications of the laboratory-produced columns are illustrated with capillary gas chromatographic separations of standard mixtures. Possible contributions of the OV-1701 -vinyl deactivation layer to both crosslinking and surface bonding in the immobilization process are discussed.

## Abstract This article presents a preliminary description of the influence exerted by vinyl groups on the process and on the result of immobilization. Vinyl groups may occur in the stationary phase (e. g. in SE‐54) or may be bound to the support surface by persilylation with divinyltetramethyldis
