MULTIVARIATE SENSOR ARRAYS AS INDUSTRIAL AND ENVIRONMENTAL MONITORINGSYSTEMS

The advances in the development of chemical sensors from individual pr obes to one- and two-dimensional sensor arrays will play an important role in the remote sensing of complex samples in the future. However, special attention must be given to the selectivity and response charac teristics of each sensor and to determining the best chemometric calib ration technique to use. Examples of chemical sensor arrays are presen ted by examining the role of chemometrics and the applications to fiel d problems in analytical science.
