    Key features

    Classical C8 phase, standard 50 % endcapping and 7 % carbon load, outstanding mechanical and chemical stability, suited for analytical as well as semi preparative and preparative applications

    Technical data

    C4 phase based on ultra-pure silica gel (purity > 99 %), metal content < 10 ppm, pH-stability 2 - 8, pore size 100 A, particle size 3 μm, 5 μm, 10 μm (15 μm, 20 – 45 μm on request).

    Recommended application areas

    Universal packing material for different application areas; can also be used in HIC mode (Hydrophobic Interaction Chromatography)

  • ProntoSIL 120 C4

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

    Monomeric C4 modification, no endcapping, with 5.5 % carbon content

    The ProntoSIL C4 is a classical C4 type stationary phase. Due to the bonding technology it shows an enhanced stability even at pH 1. The C4 packings show excellent properties for the separation of large biomolecules like proteins and peptides not only in the RP-mode but also in the HIC-mode (Hydrophobic Interaction Chromatography). The C4 bonding type is available in several pore sizes and in particle sizes of 3 μm, 5 μm and 10 μm.

  • Eurosil Bioselect 300 C4

    Eurosil Bioselect C4 is an ultra pure, spherical wide pore HPLC phase based on wide pore silica gel. The material is unpolar, with monomeric C4 modification, conventionally endcapped with a 2 % carbon content.

    Eurosil Bioselect 300 C4 has been specifically developed for the determination and purification of peptides, proteins, and oligonucleotides up to MW approx. 100,000 Da. The optimized manufacturing process guarantees excellent batch–to-batch reproducibility. The Eurosil Bioselect sorbent is the first choice for biochromatography with silica material and recommended for hydrophobic and hydrophilic interaction.
