Normal phase HPLC | Fats or fat-soluble compounds | USP L-03 class.
These HPLC columns are made with our proprietary, 5um, un-modified, High Purity Silica (HPS™) with a narrow particle size distribution. The metals content is below 1ppm which makes these columns efficient and durable.
Silica columns are most often used in normal phase mode with non-polar HPLC solvents but the Cogent HPS™ silica columns can also be used in HILIC mode with HPLC grade acetonitrile and water.

NOTE: Our technical support team strongly recommends that the Cogent column filter, included with each column, be used with all HPLC columns whenever possible. Click HERE for details.
