摘要：

A multisensor system has been developed that is capable of discriminating between complex vapours or gaseous mixtures. The system is based on an array of 12 discrete tin oxide semi-conductor sensing elements, each possessing different characteristics whilst being sensitive to a broad spectrum of gases. A weighted fault-tolerant least-squares method is used to analyse the multisensor data. Results show the multisensor system successfully discriminates (100%) between methanol, ethanol, propan-2-ol and butan-1-ol. Its overall ability to distinguish between beverages and spirits or mixtures is somewhat lower (83%) underpinning a need in this case for complementary sensing materials. © 1990.
