Electronic tongues, i.e. sensor arrays designed to characterize liquids, are not as widely used today as electronic noses. However, there are appUcations which should be taken seriously, as is clear from Table 10.2.

The problem of multianalyte analysis is of high importance in different methods of analytical chemistry. The measurements with sensor arrays are not an exception they are always complicated by multicomponent calibrations, as the number of these calibrations, even if defined in accordance with the modem principles of experimental design, increases exponentially with the increase in the number of analytes. 

In some applications, silver/silver chloride or calomel electrodes are considered cumbersome to use and maintain. More importantly, they are extremely difficult to miniaturize particularly with regard to their combined use with potentiometric membrane electrodes (see Section 18a.4.5.4) that have been fabricated into highly miniaturized and compact screen-printed sensor arrays for clinical use. Thus, several reference electrodes are manufactured with the same polymeric materials that are needed to design the responsive ion-selective membranes [7]. Incorporation of suitable active agents into such membranes leads to potentiometric responses that are ideally independent of the sample... 

As can be summarized from this survey dye-doped beads represent very versatile analytical tools which are applied in various fields of science and technology. The size of the particles is of the utmost importance here. The smallest beads are mostly designed for intracellular monitoring of analytes and much larger beads are often used in composite materials and sensor arrays. Sensing schemes for optical che-mosensors are established and are similarly realized on nano- and microscale.

The simplest form of pattern comparison (euclidean distance in 16-diraensional space) was used to design and build an operational portable gas monitoring unit (15). With the limited computer power of a portable instrument, any one of about a dozen gases could be identified In less than one minute of computational time. This algorithm was evaluated using a data set for repeated runs of 16 different chemicals in 2 different sensor arrays (14). The results... 

The data processing of the multivariate output data generated by the gas sensor array signals represents another essential part of the electronic nose concept. The statistical techniques used are based on commercial or specially designed software using pattern recognition routines like principal component analysis (PCA), cluster analysis (CA), partial least squares (PLSs) and linear discriminant analysis (LDA).
