Cogent HPS™ HPLC Columns are designed for the modern chromatography laboratory and are based on years of product development and research. Offering advantages due to lack of silanol activity as a secondary mechanism, extremely low metal content and painstaking control of the production process, the Cogent HPS™ HPLC Columns are excellent choices for all types of analytes including bases, neutrals and acids. High efficiency and excellent symmetry.

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!
