In this project the feasibility will be studied of preparing and certifying reference materials appropriate to the measurement of sulphur dioxide, nitrogen dioxide, carbon monoxide and benzene in ambient air. The project will address reference materials for 'reference methods' specified in EC directives as well as for methods based on diffusive sampling. The levels of the compounds will be appropriate to the limit values set in the directives. The project will consist of a desk study to identify optimum technologies for preparation and certification, the preparation and testing for homogeneity and stability of small batches of reference materials, and their external verification by a limited number of laboratories. The project will result in protocols becoming available for the preparation and certification of these reference materials.
