Metrohm - Model Metrosep A Supp 10 - 250/2.0 6.1020.230 -Column
The Metrosep A Supp 10 - 250/2.0 separation column is based on a high-capacity polystyrene-divinylbenzene copolymer with a particle size of only 4.6 µm. This proven column concept optimized by Metrohm is characterized by its robust construction, great selectivity and outstanding separating efficiencies. The 2 mm Metrosep A Supp 10 separation columns are packed with the same material as the corresponding 4 mm separation columns. Temperature, flow and eluent composition can be used to modify the properties of the column to accommodate the current application directly.
The Metrosep A Supp 10 - 250/2.0, as a microbore column, has a very high capacity. It is suitable for samples with high ionic strength, for complex separation tasks and for analyses in which great differences in concentration between the individual components are present. Thanks to its low flow, this microbore separation column is ideally suitable for IC-MS applications.
