Eurospher II 100-5 C18A with precolumn, Column 50 x 4 mm

Ultra pure, spherical high performance HPLC phase based on silica gel

Polar, monomeric C18 (Octadecyl) modification, polar endcapping, with 10 % carbon content (~ 50 % endcapping)

Properties

Separation mechanism: Hydrophobic and polar interaction

Key features

C18 A phase with alternative, more polar selectivity, suited for the use with pure aqueous mobile phases, 50 % endcapping and resulting 10 % carbon content, outstanding mechanical and chemical stability, suited for analytical as well as semi preparative and preparative applications

Recommended application areas

Polar endcapped C18 phase for water soluble and polar analytes, 100 % aqueous eluents for analysis of very polar compounds, basic pharmaceutical ingredients, water soluble vitamins, catecholamines as well as organic acids.
