Stationary-phase
WebAug 15, 2024 · The stationary phase is usually agrose or a porous glass bead that is able to immobilize the bonded molecule. It is possible to change the elution conditions by manipulating the pH or the ionic strength of the binding ligand. This method is often used in biochemistry in the purification of proteins. Webphase than the solutes that prefer the stationary phase. As the solutes move through the stationary phase they separate. This is called chromatographic development. How it works In all chromatography there is a mobile phase and a stationary phase. The stationary phase is the phase that doesn't move and the mobile phase is the phase that does move.

The mobile phase, a liquid, is added to the top of the column and flows down through the column by either gravity or external pressure (flash chromatography).
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 ...
