Physical Methods in Chemical Analysis, Volume III focuses on the application of physical methods in chemical analysis, including chromatography, spectroscopy, nuclear magnetic resonance, and photometry. The selection first offers information on gas chromatography, electrochromatography, and electroanalytical methods in trace analysis. Discussions focus on analytical applications, apparatus and techniques, titration methods, anodic stripping of deposited metals, and polarography. The book then examines the high-frequency method of chemical analysis, field emission microscopy, and theory and principles of sampling for chemical analysis. The publication takes a look at flame photometry and microwave spectroscopy. Topics include sample treatment required for flame photometric determinations; factors affecting precision and accuracy in flame photometry; theoretical background of microwave spectroscopy, and problems connected with quantitative analysis. The manuscript then elaborates on analytical applications of nuclear magnetic resonance; fluorescent x-ray spectrometric analysis; and neutron spectroscopy and neutron interactions in chemical analysis. The selection is a dependable reference for readers interested in the application of physical methods in chemical analysis.
