Allsep anion is a methacrylate based phase with quaternary ammonium functional groups, optimised for use with both suppressed and non-suppressed conductivity detection. They are recommended for applications involving inorganic anions, weak and strong acid ions, metal complexes and organic acids.

• pH range of 2 to 10
• Can be used with 0 to 100% organic modifier

These columns are compatible with common ion chromatography mobile phases, such as carbonate, bicarbonate, p-hydroxybenzoic acid, phthalic acid, succinic acid and sodium octane sulphonate.
