The resin backbone consists of cross-linked poly [styrene divinylbenzene]. A polyhydroxyl surface coating provides low ...
Ion exchange Definition & Meaning - Merriam-Webster
WebIon exchange chromatography is commonly used to separate charged biological molecules such as proteins, peptides, amino acids, or nucleotides. The amino acids that make up proteins are zwitterionic compounds that contain both positively and negatively charged chemical groups. Depending on the pH of their environment, proteins may carry … WebOur ion exchange (IEX) resins are rigid polymeric beads with covalent surface chemistries, which enable easier handling and packing while offering superior physical and chemical stability—resulting in a robust manufacturing process. fixture tooling
