摘要: 将多个表面涂有不同选择性吸附材料的压电晶体传感器组成阵列,用于混合有机溶剂蒸气中乙醇的检测。对阵列输出的数据,采用逐步判别法进行二类判别,可以检测混合蒸气中少量的乙醇;采用主成分回归法,可由阵列输出数据预测未知样品中乙醇的浓度。

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
