This Cogent NP Silica™ Wide Pore Stationary Phase has been a premium value and used by HPLC laboratories for many years. This low metal content, 300A, very high purity Silica is not modified in any way and is ideal as an Alternate in any USP Method that uses the L3 Classification for large molecules or for new methods.

With a 5 µm Particle and 300A Pore Size, this column works well with higher flow rates and lower back pressures.

Often used for large hydrophilic or polar compounds in HILIC or Normal Phase HPLC.
