β¦ Synopsis
The columns listed in Table 2 were further crosslinked with azo-tert-butane 181, and their high efficiencies were still retained after crosslinking. These nonextractable columns have been successfully used in supercritical fluid chromatography [9].
In summary, small diameter capillary columns have been statically coated with SE-54 at elevated coating temperaturessuccessfully.
The methodshould prove equallysuccessfulforthe preparationof nonextractable, highly efficient columns coated with other stationary phases in other solvents. This should facilitate the use of small diameter capillary columns in both gas and supercritical fluid chromatography.

In a previous paper the enhancement of solvent and solute diffusion upon alloying was discussed at high temperatures in terms of the complex model of Dom and Mitchell and its application to diffusion by Hehenkamp et al., regarding the solute atoms as being randomly distributed around vacancies and i
