WebFor example, in cation exchange chromatography, using a functional group on the solid support with a pKa of 1.2, a sample molecule with a pI of 8.2 may be run in a mobile phase buffer of pH 6.0. In anion exchange chromatography a molecule with a pI of 6.8 may be run in a mobile phase buffer at pH 8.0 when the pKa of the solid support is 10.3.

WebThere are two (major) possibilities: 1) Unmodified silica (which has a strongly polar surface) is being used with a non polar solvent — this is known as "normal phase chromatography". 2) Silica modified with hydrophobic groups is being used with a polar solvent — this is known as "reverse phase chromatography". WebIon-exchange chromatography is a type of chromatography that separates analytes based on charge. A column is used that is filled with a charged stationary phase on a solid support, called an ion-exchange resin. Strong cation-exchange chromatography preferentially separates out cations by using a negatively-charged resin while strong …
