Introduction to Hydrophobic Interaction Chromatography (HIC)

WebThe principle for protein adsorption to HIC media is complementary to ion exchange and size exclusion chromatography. Sample molecules containing hydrophobic and hydrophilic regions are applied to an HIC column in a high-salt buffer. The salt in the buffer reduces the solvation of sample solutes. As solvation decreases, hydrophobic regions that ... Webionised substances by ion exchange. Ions The soluble, ionised substances are present in water as ions, which are electrically charged atoms or molecules. The positively charged … WebSize exclusion chromatography (SEC), also known as gel filtration, is the mildest of all the chromatography techniques. SEC separates molecules by differences in size as they pass through a resin packed in a column. Unlike techniques such as ion exchange chromatography (IEX) or affinity chromatography (AC), molecules do not bind to the ... truffe nexi
