WebChemistry -Paper Chromatography Lab Chromatography is used to separate mixtures of substances into their components based on small differences in solubility of different molecules. To begin the process, you must dissolve a substance (called the mobile phase) into a second substance (called the stationary phase). The mobile phase flows through … Webmigrate in a chromatography set-up depends on the polar nature of the solute (ink) and solvent (chromatography solution).

WebIn column chromatography, a solution of a mixture of compounds is applied to be separated to the top of a vertical glass column and then it is washed down with solvent. In column chromatography, a major advantage is that the purification of compounds obtained is very high compared to other techniques such as recrystallization. WebHigher the solubility in the mobile phase, the faster the molecule will move through the column. So, the interplay between the above two factors determines the differential rates at which the different components of the analyte will move through the column. bys5ccrrna
