## Abstract We report a simple method for the preparation of silica PLOT columns using fused silica capillaries. In this method, silica particles were suspended in a methylene chloride/pentane solution containing polymethylhydrosiloxane and passed through the capillary tubing. This caused the silic

โฆ Synopsis
A new procedure for the preparation of porous silica spheres is described, which enables very small particles with a narrow size range to be prepared. Furthermore, the parameters of the pore structure can easily be controlled by the reaction conditions. In this way, porous silica supports of high efficiency were developed for the different types of liquid chromatography.
