Metrosep Anion Dual 2 - 75/4.6

Metrosep Anion Dual 2 - 75/4.6
Order number: 6.1006.100

The Metrosep Anion Dual 2 - 75/4.6 is based on an acrylate polymer. Without chemical suppression, it can be used with conventional phthalic acid eluents and a range of other eluent systems. The advantages of working without chemical suppression – simple analytical method and linear calibration – can thus be taken advantage of.

When used with chemical suppression, the column impresses with its outstanding separating efficiency, particularly with respect to the ions which elute early (fluoride, acetate, formate). The separation between fluoride and the "water dip" and between chloride and nitrite is remarkable.

    Metrosep RP 2 Guard/3.5
    General guard column. For Metrosep Anion Dual 2 and Dual 3 in particular.
  • Metrosep RP 3 Guard HC/4.0
    Metrosep RP 3 Guard HC/4.0

    The Metrosep RP 3 Guard HC/4.0 is a guard column for universal use. It reliably protects the analytical separation column against contamination, securely removing lipophilic organic contamination, the smallest particles, traces of iron oxide and bacteria. The guard column is based on a polymer material and thanks to its larger pack volume, has a significantly higher capacity that the Metrosep RP 2Guard/3.5. It can be used in the entire pH range.
