To meet high expectations concerning precision and accuracy of reference materials, preparation of matrix-free reference materials using thermal decomposition-gas chromatography-mass spectrometry (TD-GC-MS) was proposed in this study. In the paper, the results obtained in preparation of the new reference materials for benzene and toluene are presented, based on the thermal decomposition technique of compounds chemically bound to the surface of optical fibre segments. The results obtained at various stages of the research procedure (homogeneity, stability) confirmed the possibility of using prepared laboratory samples of materials as reference materials for benzene and toluene. For the prepared batch of materials, reference values 1.26 ± 0.91 (ng/fibre) for benzene and 11.3 ± 7.4 (ng/fibre) for toluene were determined.

The results of a study to evaluate a recently developed denuder sampling system for the determination of aromatic hydrocarbons in air are presented. Denuders of different lengths were tested in laboratory experiments by means of dynamically generated test gases at conditions similar to those at workplaces. Uptake rates, adsorption capacities as well as desorption efficiencies were measured at different sampling parameters. The influence of air humidity on the adsorption behaviour was determined. Finally, the suitability of the system for outdoor air investigations was checked. The denuders were very suitable for the determination of aromatic hydrocarbons in workplace air; the general feasibility to investigate outdoor air samples was demonstrated.
