KNAUER columns with C8 modification

  • Eurospher II 100 C8
  • Eurospher I 100 C8 
  • Eurosil Bioselect 300 C8
  • 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)

    Properties

    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

    Technical data

    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.

  • Eurospher I 100 C8 

    Spherical high performance HPLC phase based on silica gel

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

    Eurospher C8 packing materials can be universally used in different application areas and have been on the market for more than 25 years. The endcapped, less hydrophobic Eurospher C8 material can be used for the determination of water soluble vitamins, steroids, catecholamines, sedatives and many other applications fields. The stationary phase is stable in a pH range of 2 - 8.5.

  • Eurosil Bioselect 300 C8

    Eurosil Bioselect 300 C8 is an ultra pure, spherical wide pore HPLC phase based on wide pore silica gel. The material is unpolar, with a monomeric C8 modification, conventionally endcapped with a 4.5 % carbon content.

    Eurosil Bioselect 300 C8 has been specifically developed for the determination and purification of hydrophilic biomolecules, peptides, proteins, and oligonucleotides up to MW approx. 20,000 Da. The optimized manufacturing process guarantees excellent batch–to-batch reproducibility. The Eurosil Bioselect sorbent is the first choice for biochromatography with silica material by hydrophobic interaction.
