Abstract

Abstract: An array containing 9 piezoelectric crystal sensors is used for the qualitative and quantitative analysis of ethanol vapor mixtures.The data obtained from the array have been treated by using stepwise discrimination algorithm and principal component regression.The array can successfully discriminate between ethanol containing mixture and the mixtures without ethanol.It can be predicted the conc.of ethanol vapor in oganic solvent mixtures

Key words: Array, Piezoelectric crystal sensor, Determination of ethanol vapor
