Normal phase, ANP or HILIC | Silica-C™ is unique | Fat soluble vitamins.
Un-modified silica and silica hydride phases are useful for polar compounds in normal phase (NP), aqueous normal phase (ANP) and/or HILIC HPLC modes. Choose either from TYPE-C™ silica hydride or ordinary type-B silica for a wide range of selectivity.
A common use for silica columns is to retain polar compounds such as steroidal structures, fats, fat soluble compounds and others.
Cogent Silica-C™ - Un-modified TYPE-C™, silica hydride. This unique phase works well in NP separations with the benefits of a hydrophobic Silica surface including rapid equilibration. No need to manage water content of your mobile phase for precise results.
Cogent NP Silica™ - Made with world class type-B silica; these workhorse columns are packed and ready to be used in normal phase or HILIC HPLC.
Cogent HPS Silica™ - Proprietary base deactivated, 5um, type-B silica, these columns are great for USP L03 methods.
Cogent MicroBee Silica™ - Comparable to Waters µBondapak®, these un-modified silica columns are a great alternate for your USP® L 03 methods.
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.
