Abstract: | Monolithic sorbents for gas chromatography obtained in quartz capillaries are analyzed by means of kinetic curves (Poppe plots). The values for the time of a theoretical plate and the maximum number of plates are found to be strongly dependendent on the parameters of monolith synthesis, i.e., the relative amount of a monomer in the initial mixture, the temperature, and the polymerization time. Synthesis conditions are established using the kinetic curves, allowing the preparation of sorbents suitable for both performing high-rate analysis and achieving the most effective separation. It was shown that plotting kinetic curves on the basis of van Deemter curve data requires we allow for the compressibility of mobile phase. |
