Xtimate HPLC column derives its outstanding performance from a special hybrid particle based technique, which coats a unique 5nm organic/inorganic polymer layer on the silica surface, so that the pH range is extended to 1.0-12.5. Xtimate column is designed for HPLC method development. Regardless of the types of mobile phase or high temperature, Xtimate HPLC column always has stable performance and long lifetime.
Xtimate C4 (300Å) is based on the Xtimate series of high-purity silica gel bonded with butyl functional groups. Using 300Å large pore silica gel, it can better meet the analysis needs of biomacromolecule samples such as proteins.

    Comparison of Peak Shape After Soaking In Base

    After test at pH 12 condition for 4h, the peak shape of hybrid particles based Xtimate column shows no difference.
    Ultisil XB-C18 provides good peak shapes in the separation of these three compounds under pH 7.6, which indicates Ultisil silica contains hardly any metals.

    Lifetime Test Comparison: 5 Times Longer Than Gemini

    Unprecedented Peak Shape

    At mid pH, strong bases usually exhibit bad tailing due to secondary interactions between the analytes and the surface silaols. In Welch’s unique technique, the hybrid layer totally covers the surface silanols and blocks analytes’ access to these surface silanols. Improved bonding and endcapping further reduce silanol activity. As a result, hybrid particle based Xtimate columns show unprecedented peak shape.
