Venusil® Family of HPLC Columns

Venusil® HPLC columns are manufactured from the highest purity spherical silica particles on the market. The outstanding properties of the HPLC phases are results of subjecting high quality silica to Bonna-Agela’s innovative surface modificationand unique bonding processes. Our proprietary nanosurface modificationgenerates a very smooth and even surface. This reduces the interaction between the silica surface and polar compounds, resulting in symmetric peak shape even for very basic compounds. Based on this technology, a series of unique columns was developed to meet the tough requirements for the analysis of highly polar compounds. Lot-to-lot reproducibility is ensured by a stable bonding/end-capping process.

  • Venusil XBP

    Venusil XBP C18 columns have the maximum bonding density and therefore provide highest hydrophobicity or lowest polarity. This allows for the least interaction between the analytes and the silanol groups. Venusil XBP columns have extraordinary column stability at high pHs.

  • Venusil XBP C18(2)

    Venusil XBP C18 (2) column's packing material is made with ultra pure silica. The silica surface is processed with Bonna-Agela' s patented surface deactivation technology, followed by a unique bonding process which can reduce the carbon content while maintaining a uniform bonding coverage.

  • Venusil XBP C18

    The Venusil XBP C18 column does not have excessive retention for highly hydrophobic compounds, and it is great for the separation of acidic, basic, and neutral compounds. Moreover, this column also has superb resolution power for isomers. The perfect peak symmetry offered by this RP column makes it a great first-choice for HPLC method development.

  • Venusil XBP (L)

    XBP C18(L) has an identical bonded phase as XBP C18. However, XBP C18(L) has relatively low surface area which could shorten the retention time and analysis time.

  • Venusil SCX

    Made of spherical silica particles of the highest purity (>99.999%), bonded with aromatic sulfonic acid group.

  • Venusil SAX

    The stationary phase is made with high purity spherical silica particles and bonded with quaternary amine groups.

  • Venusil Diol

    Venusil Diol column is based on ultra high purity silica gel matrix. Dihydroxypropane groups chemically bonded to porous silica particle. Because the glycol base is less hydrophilic than pure silica silanol, it has a different selectivity from silica column. It can be widely used for polarity of natural products, herbicides and metabolites, low sugar and lipid analysis.
