This is a monograph on the subject of the theory of Stripping Electronanalytical Methods (SEAM) and its application to environmental monitoring. The simplest explanation of this phenomena is to describe it as the determination of compounds that are absorbed strongly to the electrode surface at one potential and then are stripped off at a different potential. This method is used most often for organic and biological molecules, and is useful in a number of applied areas of research, notably environmental monitoring, pharmaceutical and clinical/biochemical analysis and powder materials

This study demonstrates how the information theory approach to experimental data can be of benefit not only to analytical chemists but to all those using these techniques in the decision-making process. It deals with theoretical fundamentals as well as with practical aspects. A particular emphasis is the systems nature of analysis, which is of particular importance in multicomponent analysis.

This multi-author, edited volume includes chapters which deal with both basic and highly complex applications. Glow discharge devices are now being used in very novel ways for the analysis of liquids and gases, including molecular species detection and identification, an area that was beyond the perceived scope of applicability just ten years ago. It is expected that the next decade will see a growth in the interest and application of glow discharge devices far surpassing the expectations of the last century.
