Allsep™ Anion HPLC columns are developed for ion chromatography. In the past, the original manufacturer was Grace Vydac. Since 2016, the product line belongs to the English specialist Hichrom. The base material is a spherical methacrylate-based polymer with a particle size of 7 µm. These columns are compatible with common IC mobile phases: carbonate, bicarbonate, p-hydroxybenzoic acid, phthalic acid, succinic acid, and sodium octane sulfonate. They can be used both with and without suppressed conductivity. Allsep Anion IC columns are well suited for the EPA Method 300.0 Part A "Determination of Inorganic Anions in Water".
