Metrosep A Supp 10 - 50/4.0

Metrosep A Supp 10 - 50/4.0
Order Number: 6.1020.050

The Metrosep A Supp 10 - 50/4.0 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, high selectivity and outstanding separating efficiencies. High plate numbers and the favorable position of the system peak between fluoride and chloride supplement its properties. Temperature, flow and eluent composition can be used to modify the properties of the column to accommodate current applications directly.

The short length in conjunction with the relatively low overall capacity of this 50 mm column enable rapid separations of standard anions. They can be determined in less than 9 minutes at a flow of 1.0 mL/min. The Metrosep A Supp 10 - 50/4.0 is well-suited to simple separation problems and uncomplicated matrices.
