Summary

A procedure for the preparation of glass capillary columns coated with non-extractable phenyl polysiloxanes has been developed, the phenyl silicone being synthesised in situ in the column. The non-extractability can be explained in terms of a certain degree of crosslinking in the polymer and possibly also by some chemical bonding to the capillary glass wall. Rearrangement of the film at higher temperatures is counteracted by crosslinking in the phase. Column bleeding is thus decreased, and column efficiency is maintained even at higher temperatures. Such capillary columns showed suitable selectivities for separation of polyaromatic hydrocarbons, and the high temperatures necessary for these analyses could be attained.
