Abstract
A piezoelectric crystal sensor al:ray has been prepared as a vapour se nsing system by coating with 12 adsorptive materials selected using cl uster analysis. The frequency shift data obtained from the array as th e response patterns for the vapour of aliphatic alcohol homologues and isomers are treated by principal component analysis. The two-dimensio nal display of the original and autoscaled data show well-defined clus ters for different alcohol homologues and isomers. The method has been used for discrimination of commercial beverage samples.
