Silica Columns
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 work horse 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.
