Summary

Controlled porosity glasses (CPG) with boron atoms on their surface can be used as supports for chemically bonded phases. Increasing concentration of boron on the CPG surface causes increasing density of octadecyl siliane [ODS] chains. The properties of such films bonded to glass are different from those on silica gel surfaces. The phase transition characteristic for ODS films on silica does not occur in the case of the CPG investigated. Moreover the structure of these films seems to be more rigid.
