Descrizione generale
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 in order to choose a stationary phase. SP-2100 is a methyl silicone fluid suitable as stationary phase.
Sintetizzata appositamente per risultare più pura, con range di peso molecolare ristretto e senza impurità o catalizzatori in tracce per l′impiego come fase stazionaria per la GC.
Applicazioni
SP-2100 fused silica column deactivated with Carbowax 20M is suitable for determining optimal conditions for the analysis of fatty and resin acids in wood resin.
