Chromalite PCG consists of a product range with different porosity and particle sizes, all with identical chemistry and hydrophobic adsorptive characteristics. Chromalite PCG are highly crosslinked porous polydivinylbenzene adsorbents designed for adsorption, reverse phase chromatography and solid phase extraction. The controlled pore size and matrix have been specifically designed for purification by reversed phase chromatography, extraction and adsorption of biomolecules including proteins, peptides, oligonucleotides and antibiotics.

Principal Applications

  • Reverse phase chromatography
  • Adsorption of biomolecules up to 14KDa
  • Solid Phase Extraction


  • Highly hydrophobic adsorbent
  • High chemical stability (tolerates all common organic solvents)
  • High chemical stability
  • More robust than silica materials
  • Easy to pack in columns
  • Regenerable using standard procedures
