Metrosep Anion Dual 2 (6.1006.100)
The Metrosep Dual 2 IC anion column is based on anacrylate polymer. Without chemical suppression it
can be used with normal phthalic acid 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 taken advantage of.With chemical suppression the column impresseswith its outstanding separation performance, parti-
cularly 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 columneven further we recommend the use of the Metro-
sep RP Guard (6.1011.020). Carrier materialPolymethacrylate with quaternary ammonium groupsColumn dimensions75 x 4.6 mm
