Eurospher II 100 C8
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)
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
C8 phase based on ultra-pure silica gel (purity > 99 %), metal content < 10 ppm, pH-stability 2 - 8, pore size 100 A, particle size 2 μm, 3 μm, 5 μm, 10 μm (15 μm, 20 – 45 μm on request).
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.
