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.

The Metrosep I Trap 1 - 100/4.0 column is used to eliminate ionic, i.e. cationic and anionic, contaminants from aqueous solutions. Its use is especially recommended for the purification of the transfer water in combination with "MISP" or "Metrohm Inline Sample Preparation". Using the Metrosep I Trap 1 - 100/4.0 column can significantly reduce the influence of the transfer water on the system blank.
