WebSep 29, 2024 · Pick a Stationary Phase. Like in all other chromatography methods, column chromatography separates the components of a mixture based on their properties and how they interact with the stationary phase and/or mobile phase. The stationary phase is a matrix or resin with functional groups that interact with your sample. WebChoosing of stationary phase greatly depends on the nature of analyte. Stationary phase will depend and vary simultaneously if analyte is lipophilic or an ionic compound. In order to increase separation and increase mass transfer there have been new addition to column packing material apart from the widely used silica.
WebAug 15, 2024 · The stationary phase he used was powdered chalk and aluminia, the mobile phase in his separation was the solvent. After the solid stationary phase was packed into a glass column (essentially a long, hollow, glass tube) he poured the mixture of plant pigments and solvent in the top of the column. WebThe stationary phase is polar and retains the polar yellow dye most strongly. The relatively non-polar blue dye is won in the retention competition by the mobile phase, a non-polar solvent, and elutes quickly. Since the blue dye is most like the mobile phase [both are non-polar], it moves faster. It is typical for normal-phase chromatography on ...
