Chromatography is an analytical technique whereby a mixture of chemicals may be separated by virtue of their differential affinities for two immiscible phases and this involves traditional analytical instruments of significant size and cost, such as gas chromatograph-mass spectrometer (GC-MS), and therefore on-line, real-time analyses are difficult to realise. In this paper we report on the development of a portable microsystem and the evaluation of innovative micromachined gas sensor array performance for wine quality analysis, monitoring different blend of Apulian wine, looking towards new applications into fast and cheap miniaturized multisensor systems in a more general food quality scenario.
