Description

General description

Synthesized specifically to be purer, of narrow molecular weight range, and without trace catalysts or impurities for use as a GC stationary phase.

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. β,β-Oxydipropionitrile (ODPN) is an organic liquid phase suitable for partition chromatography.

Application

ODPN may be used as stationary liquid phase in an experiemental procedure done in order to cpmpare mixed packing gas chromatography (MPGC) and mixed liquid gas chromatography (MLGC) on the basis of the factore like their retention ability, column efficiency and tailing reducing effect.
