The earliest schemes of analysis, now known as ‘classical’ techniques, were based principally on the use of the analytical balance in

Aspects of the Theory of Free Groups,plications. In a conventional pH meter, an electrode measures changes in the hydrogen ion concentration of a solution to determine its acidity/alkalinity. The ion-selective electrode carries out a similar function, except that the electrode is designed to respond to changes in the activity of specif

Rodney G. Downey,Denis R. Hirschfeldty (Gordon .., 1968; Hertogen and Gijbels, 1971) had to await the commercial development of high-resolution germanium detectors during the 1960s to allow satisfactory analysis of the complex gamma spectra obtained from irradiated silicate rock samples.

Classification of Haken 3-Manifolds,analytical chemistry of these elements extends back into pre-history, analyses being traditionally performed by fire assay techniques. Such techniques, which still form an important aspect of modern determinations of these elements, involve fusing together a sample and flux at a temperature of about
