Because of the unique silica surface, Cogent TYPE-C Silica can bond with any chemical moiety which possesses either a terminal double or triple bond. Due the resulting strong chemical bond between silicon and carbon, these bonded phases are much more stable and resistant to conditions that can cause hydrolysis.

Initial products using the above bonding include Cogent TYPE-C Silica™, Cogent UDC-Cholesterol™ (10 carbon straight chain with an ester linkage to cholesterol) on TYPE-C Silica™, and Cogent Bidentate C18™ on TYPE-C Silica™. These products will be sequentially released starting March 2003. The particle size is 4µm, the pore size is 100A with 300A phases to be released during the year.
