Progress in Analytical Atomic Spectroscopy, Volume 7 is a collection of papers that covers the advances in analytical atomic spectroscopy. The book presents nine articles that cover areas such as methodologies and applications. The text first details the diagnostic opportunities of high voltage discharges, and then proceeds to presenting the practical applications of signal-to-noise treatment in analytical spectrometry. The next two chapters cover laser vaporization and ionization. Chapter 5 discusses the models in electrothermal atomization, while Chapter 6 tackles microwave induced plasma. The seventh chapter details equidensitometry. In the eighth chapter, the book talks about a study of sample volatilization in a graphite furnace by means of atomic and molecular absorption spectra. The last chapter covers the image sensor application in analytical spectrometry. The text will be of great use to chemists who aim to expand their knowledge in analytical spectrometry.
