✦ Synopsis

Abstract

A detailed method for the routine preparation of glass capillary columns is presented. The method consists of coating a glass tube with quartz powder prior to pulling the tube into a capillary. The inner surface of the capillary consists of an even distribution of quartz particles fused to the walls. This surface has been found readily deactivated by standard procedures and ideal for the preparation of thick‐film glass capillary columns. The method has been thoroughly tested in two independent laboratories to ensure that the procedures described are reproducible.
