  • Eurospher II 100 C18
  • Eurospher I 100 C18 
  • Eurosil Bioselect 300 C18
  • Eurospher II 100 C18 

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

    Unpolar, monomeric C18 (Octadecyl) modification, endcapped, with 16 % carbon content (~ 50 % endcapping).

    Properties

    Separation mechanism: Hydrophobic interaction

    Key features

    High-class HPLC phase perfectly suited to take on routine analyses as well as the most ambitious chromatography tasks, classical C18 phase with ca. 50 % endcapping and resulting 16 % carbon content, outstanding mechanical and chemical stability.

    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

    • acidic, basic and neutral analytes in reversed phase mode, for example sulphonamides;
    • anabolic steroids;
    • anti-psychotics;
    • beta blocker;
    • sudan dyes;
    • phenols and preservatives

  • Eurospher I 100 C18 

    Spherical high performance HPLC phase based on silica gel

    Unpolar, monomeric C18 (Octadecyl) modification, endcapped, with 16 % carbon content (~ 50 % endcapping)

    Eurospher C18 packing material can be universally used in different application areas and has been on the market for more than 15 years. The most often used material is the endcapped Eurospher 100 C18 for the reversed phase mode, followed by the less hydrophobic Eurospher 100 C8. Both can be considered for the determination of water soluble vitamins, steroids, catecholamines, sedatives and in many other application fields in the analytical as well as preparative range. The stationary phase is stable in a pH range of 2 - 8.5. Eurospher C18 is the workhorse of reversed phase applications.

  • Eurosil Bioselect 300 C18

    Ultra pure, spherical wide pore HPLC phase based on silica gel
