Abstract
This article describes a method of preparing immobilized stationary phases which has arisen from the author's work on polysiloxane deactivation of fused silica capillaries. Although acid treatment is often omitted with fused silica capillaries, there are good reasons for hydrothermal treatment of this column material. Use of Grob's peroxide method gave immobilized 0.25 micrometers films of SE-54; lowering of the immobilization temperature permitted immobilization of 0.1 micrometers films of the same phase.
