Ion chromatography columns packed with a negatively-charged ion exchange resin designed to attract molecules with net positive surface charges. Cation-exchange columns are ideal for ion chromatography separations of inorganic cations, ammonium, and various amines.
Prepacked columns for high-resolution purification of proteins and other biomolecules by ion exchange chromatography. They are well-suited for the preparation of highly pure proteins for structural studies and protein analysis.
