Abstract: The physicochemical properties of novel mesoporous carbon sorbents and their application for the preconcentration of trace analytes in combination with HRGC are presented. For sorbent evaluation, scanning electron microscopy, elemental analysis, ¹H  MAS and ¹³C  MAS solid-state NMR spectroscopy were applied together with measurements of the surface area, particle size and shape, pore size and volume, as well as with determination of specific retention volumes of selected compounds belonging to different groups of adsorbates. The tested sorbents showed high sampling capacities and were successfully applied to the preconcentration and/or isolation of great variety of volatile compounds and semivolatile compounds from simulated samples and various environmental matrices.
