Cogent HPS Cyano
– 11 columnsCogent 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!
The Cyano phase columns are recommended for bases in reverse phase due to their highly retentive nature and tailing normally found in reverse phase chromatography
