ABSTRACT:
Packing materials for use in liquid chromatographic analysis are prepared by contacting a porous support, such as porous silica, with a ketal silane to form ketal blocked diol groups on the surfaces thereof. An end-capping reagent such as a trimethylsilyl reagent may be added. In addition, the ketal blocked diol groups may be further hydrolyzed to diol groups.
