本文提出了一种基于脉冲伏安电子舌的分类和定量技术中脉冲阵列的合理设计方法。作为模型问题，我们设计了一个程序来预测二茂铁，TCNQ和Ru（bipy）（3）（2+）使用伏安电子舌采用一组贵金属电极，即Au，Pt，Ir和Rh的水平。二茂铁、TCNQ和Ru（bipy）（3）（2+）被选为模型化合物，因为它们是具有明确氧化还原过程的分子。电极被容纳在不锈钢圆筒内，该圆筒被用作电子舌系统的主体。SCE用作参比电极。二茂铁响应的电化学研究。TCNQ和Ru（bipy）（3）（2+）的反应是第一步进行的，目的是研究这些化合物中的氧化还原过程。采用三化合物/三水平的实验设计，制备了含二茂铁、TCNQ和Ru（bipy）（3）（2+）的不同样品。采用基于偏最小二乘法（PLS）的多元分析方法进行数据管理和预测模型的建立。几组脉冲进行了测试，并讨论和提出了一个一般程序，他们的设计，他们使用的伏安电子舌。(C)2011 Elsevier B.

This paper proposes a reasonable methodology for the design of pulse arrays applied in classification and quantification techniques based on the use of pulse voltammetric electronic tongues. As model problem we designed a procedure to predict levels of ferrocene, TCNQ and Ru(bipy)(3)(2+) using a voltammetric electronic tongue employing a set of noble electrodes; i.e. Au, Pt, Ir and Rh. Ferrocene, TCNQ and Ru(bipy)(3)(2+) have been selected as model compounds because these are molecules with well defined redox processes. The electrodes were housed inside a stainless steel cylinder which was used as the body of the electronic tongue system. A SCE was used as reference electrode. An electrochemical study of the response of ferrocene. TCNQ and Ru(bipy)(3)(2+) was carried out as a first step with the aim of characterise the redox processes in these compounds. Different samples containing ferrocene,TCNQ and Ru(bipy)(3)(2+) were prepared following an experimental design in which a system of three compounds/three levels was established. Multivariate analysis based on Partial Least Square (PLS) techniques was applied for data management and prediction models building. Several set of pulses were tested and a general procedure to their design for their use in voltammetric electronic tongues is discussed and proposed. (C) 2011 Elsevier B.V. All rights reserved.
