Silica Columns

Normal phase or HILIC | Fat soluble analytes | Wide range of particle sizes | USP® L-03


This HPLC stationary phase is made from the same high purity silica and narrow particle size distribution, as Cogent RP columns. Un-modified with no carbon loading the metals content is below 1ppm making them highly efficient columns.

The Cogent NP™ Silica columns provide excellent normal phase (NP) or HILIC chromatography, are robust and reproducible. Available in a wide range of particle sizes and column dimensions to meet every need including wide average porosity (300A).
