General description
GC methods are divided into two classes depending on the nature of stationary phases; gas-solid chromatography (GSC) and gas-liquid chromatography (GLC). GSC has solid adsorptive material and solute particles are removed from mobile phase by electrostatic forces. GLC has a thin layer of liquid coated or bonded on the surface of an inert particle or on the walls of the column where solute particles are retained in the liquid phase based on their partition coefficients. The primary necessity of a stationary phase is to provide sample separation sustaining phase integrity over a reasonable period of time. It should be stable for the chemical and thermal changes. Selectivity, peak symmetry, analysis time, degree of separation, peak tailing are a few parameters that should be considered before choosing a stationary phase. OV-1 is suitable for the separation of drugs, alkaloids, phenols and steroids.
Synthesized specifically to be purer, of narrow molecular weight range, and without trace catalysts or impurities for use as a GC stationary phase.
Application
OV-1 is suitable as stationary phase for monitoring the urinary excretion in man for pentachlorophenol (PCP) and PCP conjugated to glucuronic acid using gas chromatography with electron capture detection (GC/ECD).

Pentachlorophenol (PCP) was given orally to three volunteers at single doses of 3.9, 4.5, 9, and 18.8 mg. Daily urinary excretion of PCP and PCP conjugated to glucuronic acid was monitored using gas chromatography with electron capture detection (GC/ECD). Based
