基本信息
| NACRES | SB.54 |
| General description【一般描述】 | 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. 合成的产品更纯净，分子量范围窄，不含用作 GC 固定相的痕量催化剂或杂质。 |
