The many advanced features of the Cogent UDC-Cholesterol column produces a very stable, efficient and unique HPLC column with unique selectivity for steroids and other compounds

• Not endcapped liquid crystal
• Shape recognition
• 'Steroids' column
• TYPE-C™ silica

The Cogent UDC-Cholesterol™, an eleven carbon link with cholesterol attached is bonded to the silica hydride surface with a direct silicon-carbon bond. This phase is more sensitive to heat and solvent composition than most phases due to the liquid crystal nature of the cholesterol moiety. These parameters can be used in shape recognition and can make for very unique selectivity on this very stable and robust column.

Operates in reversed phase (RP), normal phase (NP) and/or aqueous normal phase (ANP), solving many difficult separation problems.
