β¦ Synopsis
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 retention characteristics of the solutes and the optimum column length by the required magnitude of separation. The optimum carrier gas flow-rate was found to be a function of the column length. Emphasis is placed on using capillary column length as an operating parameter.

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
