  • ProntoSIL 120 Phenyl

    Spherical high performance HPLC phase based on silica gel

    Phenyl modification (Phenylpropyl), standard endcapping, with 10 % carbon content

    ProntoSIL Phenyl is a RP packing that offers different selectivities in comparison to brush type stationary phases like C8 or C18. It is fully endcapped. Due to the bonding technology it shows excellent stability even at pH 1. The ProntoSIL Phenyl packing is available in 120 Å and particle sizes of 3 μm and 5 μm. The 5 μm support is also available in 60 Å. This packing shows an enhanced selectivity and hydrophobicity.
