Metrosep A Supp 5 - Microbore 2 mm anion column for ion chromatography Anion analysis with the new Metrosep A Supp 5 - Microbore Metrohm is continually expanding its own range of 02 and materials. The result is columns with outstanding columns and is improving existing separation column separation performance, short retention times, high sta-types using state-of-the-art manufacturing processes bility and lower costs per injection.
