phases made of porous graphitic carbon can be used for normal and
reversed-phase separations over a broad range of temperatures and pHs. The
Column spoke to Harry Ritchie, chromatography consumables director, of the
Thermo Electron Corporation about the theory and practical applications of
this novel stationary phase. What is a porous graphitic carbon stationary
phase? based and polymeric phases. The material is suitable for the
separation of highly polar compounds with closely related Hypercarb or
porous graphitic carbon PGC stationary phase structures. The chemical
characteristics of this material are also consists of individual porous,
spherical particles made of different from conventional high performance
liquid graphite interconnection regions of graphitic ribbons Figure 1 .

is a series of interwoven flat sheets of The PGC packing is totally stable
across the entire pH range hexagonally arranged carbon atoms. These carbon
atoms have from 0
