✦ Synopsis

The preparation and properties of glass beads as a support for gas-liquid chromatography was studied. A comparison between diatomaceous earth type supports and glass beads was made in terms of activity to polar components. The procedure originally suggested by Grob was used to determine specific solute-surface interactions. We unexpectedly found it difficult to deactivate glass beads by conventional means. This is possibly due to the large number of silanol groups remaining on the surface of the support after deactivation. Several methods of deactivation were evaluated.
