Articlename: Eurospher II 100-5 C8 with precolumn, Column 150 x 4 mm

Eurospher II 100-5 C8 with precolumn, Column 150 x 4 mm

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

Monomeric C8 (Octyl) modification, standard endcapping, with 10 % carbon content (~ 50 % endcapping)


Separation mechanism: Hydrophobic interaction (lower compared to C18 phases)

Key features

Classical C8 phase, standard 50 % endcapping and 10 % carbon load, outstanding mechanical and
chemical stability, suited for analytical as well as semi preparative and preparative applications

Recommended application areas

Similar selectivity to C18 phase but less retention due to the lower hydrophobicity; useful for determination of water soluble vitamins, steroids, catecholamines, sedatives etc.
