## Abstract The effect of a pretreatment step on the polarity of fused silica capillary tubing prior to coating was evaluated. Columns were tested prior to and after coating with a 50% phenl stationary phase, and the chromatographic findings were compared. The results confirmed that the polarity of

The life expectancy and resistance to flow, pressure shocks, solvent gradients, and bending of packed fused silica capillary columns (Micro-LC) are discussed. ## 2 Instrumentation Chromatographic measurements were carried out on a Varian 5020 (Varian Associates, Walnut Creek, CA, USA) and on a Per
## 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
The activity of fused silica capillary tubing has been shown to vary considerably, which severely influences the reproducibility of column deactivation and inertness. Methods for producing a reproducible, high activity surface with maximum hydroxylation by various hydrothermal treatments were evalua
