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 columns is given. The influence of leaching and HTS on the temperature stability and coating efficiency of capillary columns coated with OV‐1 was studied. The inertness of the glass surface after HTS is demonstrated by several examples.

A deactivation procedure is described based on a published method using hexamethyldisilazane in the gas phase. In addition to unusually high inertia and thermostability, the method produces truly neutral columns which allow simultaneous analysis of moderately strong free acids and bases. The silylat

## Abstract The use of high‐temperature‐stable, medium polarity glass capillary columns coated with immobilized PS‐090 (a 20 % diphenyl‐substituted, CH~3~O‐terminated polydimethylsiloxane) has made it possible to analyze routinely, and with good separation efficiency, high molecular weight compound
