    Recommended application areas

    Recommended alternative to Kromasil 100 C18, für acidic, basic and neutral analytes in reversed phase mode with extended pH range

  • Eurospher II 100 C18P

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

    Unpolar, trifunctional C18 (Octadecyl) modification, high efficiency endcapping, with 20 % carbon content (~ 99 % endcapping)

    Properties

    Separation mechanism: Hydrophobic and steric interaction

    Key features

    KNAUER´s most unpolar C18 phase, polymeric, high efficiency endcapping of 99 % and 20 % carbon content, higher pH stability in the range of 1-12, outstanding mechanical and chemical stability, suited for analytical as well as semi preparative and preparative applications

    Technical data

    C18 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

    Alternative selectivity to standard C18; stationary phase in Eurospher II C18 family with the highest carbon load; fully endcapped; excellent shape selectivity and pH stability.

  • ProntoSIL 120 C18SH

    Spherical high performance HPLC phase based on type A silica gel

    Unpolar, monomeric C18 (Octadecyl) modification, endcapped, with 17 % carbon content

    ProntoSIL C18 SH is the stationary phase in the ProntoSIL line with the highest carbon load. It is fully endcapped. Due to the carbon load it shows an excellent shape selectivity and stability even at pH 1. The C18 SH-bonding type is available with a pore size 120 Å and in several particle sizes.
