摘要：

The response of an array of polymeric sensors to different Spanish wine varieties has been evaluated. Two different systems for the injection of the volatile compounds, based on static and dynamic headspace sampling, were used. A comparative study of the operation of the array when using one or the other methodology has been carried out. The cross sensitivity of the polymeric films to moisture and ethanol has been explicitly considered. The discrimination and classification capabilities of the sensor array have been examined by statistical analysis of the obtained data using pattern recognition techniques.
