Deposition of organic chemicals on historical buildings is a well-known phenomenon. Such material originates from airborne pollution, from human activity, and from natural sources, and it tends to accumulate over long times on the surfaces in the form of a black film which covers considerable portio

โฆ Synopsis
Two analytical approaches have been applied to the characterization of the aroma fraction of five Italian wines, solid-phase micro-extraction coupled with gas chromatography, and membrane inlet mass spectrometry. The first approach resulted in highly specific and reproducible data and permitted the differentiation among wine samples from the same grape but from different production areas. The second technique, notable for its short time of analysis and ease of use, exhibited a lower specificity.
