Kromasil: EternityShell


Kromasil EternityShell columns are solid core particle technology columns with the ‘Kromasil Eternity’ organosilane modifications and bonding. This provides highly stable, chemically robust and extremely pH resistant columns. Packed with 2.5um solid core particles these columns are intended for fast separations over a wide pH spectrum in support of efficient laboratory turnaround.


The general features of EternityShell phases include:

  • Solid core particle technology
  • Proprietary organic/inorganic layer
  • pH stable from 1 – 12
  • Use in both UHPLC and HPLC systems
