Weak Cation Exchanger | Liquid Crystal & Shape Recognition
Cogent TYPE-C™ Silica is the most unique HPLC Silica available. With a hydrophobic, Silica Hydride surface, partitioning chromatography is eliminated resulting in excellent selectivity for some hard to separate compounds.
Cogent UDC-Cholesterol™ - An 11-carbon aliphatic linker with a terminal cholesterol group bonded to the Silica hydride surface with a direct silicon-carbon bond.
Cogent UDA™ - An 11-carbon aliphatic linker and a terminal carboxylic acid group bonded to the Silica hydride surface with a uniqueness to exhibit weak Cation Exchange properties in addition to Reversed Phase (RP) or Aqueous Normal Phase (ANP) chromatography.
