β¦ Synopsis
Judging by the number of manuscripts recently submitted to the journal on the static coating of capillary columns, it would seem that this method is gaining in popularity. The fact that these communications contain similar technicaldetails may give the reader the impression of unnecessary repetition. It was decided, however, that most of these papers would be published in order to give the reader, and especially one who has not yet practised static coating, the chance of comparing how the method is employed in different laboratories.

Thecoating speed upon staticcoating of glasscapillarycolumns was evaluated in terms of inner diameter and length of the column, viscosity and pressure of solvent vapor, etc. From the equation obtained it can be shown that a smaller diameter of a microbore column restricts solvent vapor transfer to t
The technique of spontaneous coating of capillary columns employing liquefied butane and ethylene chloride as solvents of the stationary phase is described. These solvents and their mixtures are suitable for apolar and medium-polar stationary phases. The dependence of coating time on coating tempera
