## Abstract This paper describes the results of a study on the deactivation of the surface of glass capillary columns by high temperature silylation (HTS). The different steps, leaching, washing, dehydration and HTS were optimized. A practical procedure yielding a high percentage of very good colum
## Abstract Differently pretreated glass capillaries were coated with hydroxyβterminated methyl or methylβphenyl polysiloxane gum phases and cured at 340β360Β°C for several hours. The volatile reaction products formed during the baking procedure were analyzed and the retention behavior of various po
