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

    No modification, no endcapping, with 0 % carbon content

    Properties

    hydrophilic 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

    Bare Si 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

    Wide range of different applications, i.e. SEC (size exclusion chromatography) but also for normal phase HPLC and HILIC; good choice for analytical and preparative purposes to separate polar compounds

  • Eurospher 100 Si

    Spherical high performance HPLC phase based on silica gel

    No modification, no endcapping, with 0 % carbon content

    Eurospher 100 packing material can be universally used in different application areas and has been on the market for more than 25 years. Eurospher 100 Si is a typical representative of the first generation of high performance spherical silica gels. It is a good choice for analytical and preparative applications. Eurospher Si is available in several particle sizes and is also a good alternative for preparative purposes. Unmodified Eurospher 100 Si can be used to perform separations of polar compounds such as aflatoxins and anisoles.

  • ProntoSIL 120 Si

    Spherical high performance HPLC phase based on silica gel

    No modification, no endcapping, with 0 % carbon content

    The ProntoSIL is the silica support of the Alliance for Chromatography. Due to the fact that it is manufactured under very stringent conditions the resulting silica has a purity of 99.999%. The optimum manufacturing process guarantees an excellent batch to batch reproducibility. The silica is available in several particle and pore sizes. Therefore a wide range of different applications, i.e. in SEC (Size Exclusion Chromatography) but also for the NP HPLC of large molecules is given.
