ANIONS: IC columns used with and without chemical suppression

The Metrosep Dual 2 IC anion column is based on an acrylate polymer. Without chemical suppression it can be used with normal phthalate eluents and a range of other eluent systems. This means that the advantages of working without chemical suppression - simpler analytical methods and linear calibration - can be exploited.
With chemical suppression the column impresses with its outstanding separating performance, particularly of the ions which elute early (fluoride, acetate, formate). The separation between fluoride and the «water dip» and between chloride and nitrite is remarkable.
In order to increase the working life of the column even further we recommend the use of the Metrosep RP Guard (6.1011.020).
