ABSTRACT

In previous chapters, individual techniques that are widely used in analysis were described in considerable detail. There are obviously an extraordinarily large number of other polarographic methods that have been proposed for analytical use in an initial publication, but have not been heard of since, hopefully only because they were not all that good. Such methods need not be discussed in this book. Then again, there are other techniques which have found quite wide acceptance but have yet to be referred to. The range of techniques considered in the preceding chapters represents, in this author’s opinion, the basic selection that an analytical chemist wishing to undertake routine polarographic analysis should have access to. All of these methods have been discussed widely in the literature, are constructed from relatively simple instrumentation, and are based on well-established theoretical principles which enable them to be used in a systematic rather than empirical fashion. Furthermore, the philosophy behind modern polarographic analysis is adequately conveyed by reference to the methods already considered. However, so as not to offend too many of my colleagues, several other of the well-established polarographic techniques with distinct analytical use or claimed analytical advantage are discussed briefly in this chapter.
