Different novel fibers for solid-phase microextraction were developed in the last years. The aims of this work were the study of their performances in wine headspace analysis, and the optimization of some analytical conditions. The fibers were evaluated for their sensitivity and repeatability; the results showed a strongly different behavior for the different solid-phases, both for the different zones of the chromatogram and for different levels of concentration. A Divinylbenzene/Carboxen/Polydimethylsiloxane fiber coating appeared the most suitable for the analysis of aromatic fraction of wines in its totality. For specific applications, the choice of a suitable solid-phase, depends on the class of compounds be analyzed.
