✦ Synopsis

A method is given to prepare glass capillary columns with almost any stationary phase. The method is based on etching the soda-lime glass capillary tubing by dry gaseous hydrochloric acid. Coating the columns by the static method results in highperformance apolar and polar phase columns. The polar columns can be used even for the analysis of highly polar solutes. Studying the etched surface of soda-lime glass, the presence of a uniform layer of microcrystalline NaCl was found.

A new principle and method have been developed for producing a high-efficiency WCOT column by forming a polyimide capillary tube of l-5 pm wall thickness inside a supporting glass capillary (tube-in-tube system). This polyimide layer is chemically resistant, heat-proof (up to 450°C) and mechanically
