GC方法根据固定相的属性可分为两类;气固色谱(GSC)和气液色谱(GLC)。GSC具有固体吸附材料,且溶质颗粒可通过静电力而从流动相中被去除。GLC会有一层薄薄的液体层通过涂覆或键合在惰性颗粒的表面或色谱柱壁上,其中的溶质颗粒会根据其分配系数而被保留在液相中。固定相的主要必需条件是能够提供可在合理时间内保持相完整性的样品分离。它应当可对化学和热变化应保持稳定。选择性、峰对称性、分析时间、分离度、峰拖尾是选择固定相时需要考虑的几个参数。Synperonic PE/F68是聚乙烯和聚丙二

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 few parameters to consider for choosing a stationary phase. Synperonic PE/F68 is a block copolymer of polyethylene and polypropylene glycol and it is mostly used as surfactant.Synthesized specifically to be purer, of narrow molecular weight range, and without trace catalysts or impurities for use as a GC stationary phase.It has been used in preparation of surfactant solution while synthesising sunscreen nanoparticles embedded in lipid matrices; to understand the encapsulation effect of UV molecular absorber into lipid nanoparticles.
