Porous glass is a well suitable system for the exploration of new characterization techniques due to adjustable texture properties and the possibility to "tailor-made" the surface chemistry. In this study porous glass beads were utilized as model system for the evaluation of inverse gas chromatography (IGC). Mesoporous glass beads with 10 and 20 nm pore size and macroporous glass beads with 50 nm pore size were synthesized and modified by thermal treatment and chemical reaction with hexamethyldisilazane (HMDS), ethyl-, propyl-, butyl- and octyldimethylchlorosilane. The correlations between the textural properties and the dispersive surface energy were investigated by means of the IGC technique. Furthermore dependences between surface chemistry and surface energy were pointed out on the basis of IGC measurements.
