MOST POPULAR.
Additional Info:
This Very Popular Cogent NP Diol™ Stationary Phase has been a premium value and used by HPLC laboratories for many years. Non end-capped, it is manufactured with the highest purity 100A Silica available and bonded with a short hydrocarbon ligand that has a terminal, Diol Functional group. This make this Column ideal as an Alternate in any USP Method that uses the L20 Classification or for new methods that analyzes large molecules.
With a 5 µm Particle, this column works well with higher flow rates and lower back pressures compared with smaller particles. It is often chosen to replace unmodified Silica columns in established methods, even though there may be slightly different selectivity because it can be more robust and more compatible with a wider range of solvents.
Use for hydrophilic or polar compounds in HILIC or Normal Phase HPLC.
