## Abstract The present paper describes an automated system for preparative gas chromatography with glass capillary columns, controlled by a microprocessor. The effluent from the capillary column is divided by a pneumatically controlled splitter and any desired split ratio between traps and detecto

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 c
## Abstract The proposed combination of a rather simple procedure for sample preparation with capillary gasβliquid chromatography using a barium carbonate/polyethyleneglycol 20,000 column and a Grobβtype onβcolumn injector permits measurement of bile acids in serum with high separation efficiency,
The relationship between analysis time and separation with glass capillary columns was studied. Optimal operating parameters for achieving the shortest analysis times consistent with degree of separation were determined experimentally\_ It was found that the optimum column temperature is governed by
