Metrohm, 6.0103.5420, Metrosep A Supp 20 - 150/4.0

The Metrosep A Supp 20 - 150/4.0 is an advanced anion chromatography column designed to deliver high‑quality separations for regulatory and advanced applications. Its excellent separation efficiency makes it ideally suited for methods requiring precise determination of standard anions and oxyhalides, including US EPA 300.1 Parts A and B and ISO 10304 Parts 1 and 4. With reliable performance across different sample types, it offers laboratories a stable solution for both routine and compliance‑driven anion analysis.
Built on a durable polystyrene/divinylbenzene substrate, the selectivity of the Metrosep A Supp 20 - 150/4.0 is optimized for operation with isocratic carbonate eluents, offering a particularly robust and user‑friendly solution for daily anion chromatography workflows. This ensures excellent long‑term stability, and full compatibility with widely established IC methods.
Thanks to its high anion exchange capacity, the Metrosep A Supp 20 - 150/4.0 supports the full application range typically handled by high‑capacity anion columns, including the determination of oxyhalides, standard anions and dichloroacetate. The shorter version of the Metrosep A Supp 20 series, the 150/4.0 version, provides a fast and accurate analysis across diverse sample types and is suitable for most determinations.
