Hypersil BDS


Hypersil BDS (Base Deactivated Silica) phases are widely referenced in legacy methods. They are robust, general purpose columns for use in a wide range of applications in QA/QC laboratories. Hypersil BDS columns exhibit reduced silanol activity compared to Hypersil Classical phases. For more challenging separations that require improved chromatographic performance, Thermo Scientific recommend Hypersil GOLD columns as an alternative.

  • General purpose columns
  • Reduced peak tailing for basic compounds
  • All phases endcapped
  • Good performance with acidic, basic and neutral compounds
