詳細

詳細

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. SE-30 is a dimethyl silicone elastomer. It is widely suitable as liquid phase got GLC.

GCの固定相として使用するために、純度を高く、分子量範囲を狭く、痕跡レベルの触媒や不純物を含まないように特に合成しました。

アプリケーション

SE-30 was used as stationary phase for the analysis of the thiohydantoins using GC. It may also be used as liquid phase in identification of the single polychlorinated biphenyls (PCB) components by comparing their retention indices, using high-resolution thin-film glass capillary gas chromatography coupled with electron-capture detector.
