โœฆ Synopsis

The efficiency of FSOT columns coated with thick films of polyphenylmethylsiloxane was theoretically and experimentally compared to thin apolar and medium polar coatings and to thick apolar coatings. Experimental hli and TZG plots clearly demonstrate the enormous loss in chromatographic efficiency of thick films of medium polar siloxane stationary phases. The low diffusion coefficient in the liquid phase is responsible forthis behavior. The influence of the temperature and the nature of the solute on the efficiency was also studied.

A method for preparation of capillary columns and traps with a very thick film (up to 100 pm) of stationary phase is described. The principle of this method is based on an immediate fixation of a film of prepolymer, formed during dynamic coating. Thus, the development of film irregularities, such as
