Cogent HPS™ is a stationary phase (both bonded and non bonded) that is designed for applications that require high purity silica. Metal content in Cogent HPS™ is extremely low and this produces very good stability and “deactivates” the silica for use with basic analytes. A very smooth and uniform silica surface results for mechanical strength […]
What is the biggest difference between Cogent HPS™ columns and most HPLC columns available on the market today?
The Cogent HPS™ silica has a very narrow particle size range and consequently the column efficiency and durability of the phase improves significantly. Additionally, the bonded phases have been manufactured under strict anaerobic conditions and unique bonding techniques have been employed. For this reason the bonded phases are covered uniformly on the silica surface producing […]
These columns have been determined to be very reproducible from column to column, from batch to batch by customers from all parts of the world.
These columns are extremely stable in from pH 2.0 to pH 8.6. Depending on the concentration of the acid or base will determine if these columns would be stable outside of this range. Click here to view more information about Cogent HPS HPLC columns
