Your solution for difficult separations in both reversed phase and normal phase HPLC and LC/MS applications

Porous graphitic carbon (PGC, Hypercarb™) has unique properties as a stationary phase in high-performance liquid chromatography (HPLC). Its chemical surface properties distinguish it from more conventional LC packings such as bonded-silica gels and polymers. PGC behaves as a strongly retentive alkyl-bonded silica gel for non-polar analytes.

However, its retention and selectivity behavior towards polar and structurally-related compounds is very different from conventional C18 columns.
