Notes:
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 silica particles to be dynamically coated on the inner wall of the fused silica capillary. The column was dried and heated, which facilitated the simultaneous deactivation and bonding of a uniform mono-layer of porous silica on the inner wall of the capillary tubing. These columns were used to separate light hydrocarbons, chlorinated hydrocarbons, and aromatic compounds.
