Cogent HPS™ Specifications


HPS specifications include:
  • • Monofunctional bonding
  • • Metals content that are so low, that they have virtually no impact on separation mechanisms as in older brands of silica based HPLC Columns.
  • • Particle size distribution that is so tight that no column offers greater efficiency.
  • • Pore volume that is extremely consistent due the nature of our proprietary chemical process making resolution extremely reproducible.
  • • An incredibly uniform surface area and structure, always perfectly spherical!
