Web22 apr. 2024 · Ion-exchange chromatography is a type of chromatography, which is commonly used in the purification of proteins and other charged molecules. In this technique, the molecules are separated based on their charge. In anion exchange chromatography, negatively charged molecules are attracted to solid supports with a … 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".
