Developing selective stationary phases for gas chromatography (GC) is key to achieving high-resolution separation of analytes in various samples for their GC determinations. With the rapid development of materials science, researches on employing diverse types of materials as GC stationary phases have advanced considerably. This review mainly focuses on the investigation of porous materials, graphene and analogs, truxene-based materials, and triptycene-based materials as stationary phases for GC separations over the past five years, and briefly discusses the related problems and prospects.
Keywords: gas chromatography (GC); review; stationary phase.
