Melville: Amer Inst Physics, v. 80, n. 2, p. 3, 2009.0034-6748http://hdl.handle.net/11449/42323We present a compact and easy to handle instrument developed to perform rapid analysis of liquids utilizing an electronic tongue system. Briefly, the e-tongue used here is based on impedance measurements of an array of sensing units fabricated with ultrathin films of different materials deposited onto gold interdigitated electrodes. The instrument has the capability of measuring up to eight different sensor sets, each comprising an array of eight sensing units, and can perform a series of measurements in less than half of an hour. Additionally, there is a user-friendly software interface for instrument control, allowing the statistical correlation of samples using principal component analysis.3engelectric impedance measurementelectronic tonguesgoldprincipal component analysisArtigo10.1063/1.3084210WOS:000263803500050Acesso abertoWOS000263803500050.pdf
