Abstract:Porous graphitic carbon (PGC) columns for liquid chromatography (LC) represent an alternative to octadecyl‑bonded silica columns for the separation of both polar and nonpolar molecules. This is accomplished by exploiting the polarizability of the stationary phase interacting with the functional groups of the analytes. However, the elution of nonpolar compounds requires a high percentage of organic solvent, losing the intrinsic advantage of reversed‑phase aqueous separations. In this article, we aimed to exploi… Show more
“…PGC exhibits high selective adsorption ability in separating polar uncharged species, highly polar compounds with different spatial molecular structures (including structural isomers), and ionic/charged species via high-performance liquid chromatography (HPLC). C8 or C18 reverse phases are often less effective or even fail to retain this class of compounds [9]. PGC exhibits high column efficiency for polar compounds and improved retention of compounds that typically require hydrophilic interaction liquid chromatography (HILIC) for retention.…”
