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)

Modification	Application areas	Separation mechanism
C18	for acidic, basic and neutral analytes in reversed phase mode (sulphonamides; anabolic steroids; anti-psychotics; beta blocker; Sudan dyes; phenols, preservatives etc.)	hydrophobic interaction

Similar columns from other manufacturers to Eurospher II

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated

Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.

A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.

No other-Vendor Brand family with the same Mode and Modification meets the comparable-data and similarity thresholds.
