Puritas 120Å C-18


PURITASTM ODS phases featuring maximum surface coverage are the ideal choice for a wide variety of organic compounds. Carefully controlled full end capping leads to optimal performance with acidic, basic and chelating compounds. For analytical high speed applications 12 nm phases offer a good compromise between surface area available, separation speed and solvent consumption.

Key Features

  • High coverage and exhaustive end capping
  • Exceptional batch-to-batch reproducibility
