Eurospher II

by KNAUER

 

VertexPlus Column Eurospher II                                                                       

Eurospher II is introduced as the new workhorse for an even wider range of application areas, suitable for analytical, semi-preparative and process-scale separations. The logical choice to take on routine analyses as well as the most ambitious chromatoraphy tasks.

Eurospher II offers outstanding mechanical and chemical stability. With physical properties very similar to those of Kromasil 100, Eurospher II columns can be used to replace Kromasil® columns, providing excellent peak symmetry for acids, bases, and neutrals. Compared to Kromasil® 100, Eurospher II has

  • nearly the same particle shape
  • a lower metal impurity specification
  • higher mechanical stability
  • comparable selectivity in RP mode (Eurospher II C18 H vs. Kromasil® 100 C18)
