Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. Analytical chemistry applications is largely driven by performance and cost. Among the main branches of contemporary analytical atomic spectrometry, the most widespread and universal are optical and mass spectrometry. In the direct elemental analysis of solid samples, the new leaders are laser-induced breakdown and laser ablation mass spectrometry, and the related techniques with transfer of the laser ablation products into inductively coupled plasma. Advances in design of diode lasers and optical parametric oscillators promote developments in fluorescence and ionization spectrometry and also in absorption techniques where uses of optical cavities for increased effective absorption pathlength are expected to expand. The use of plasma- and laser-based methods is increasing. An interest towards absolute (standardless) analysis has revived, particularly in emission spectrometry. Analytical methods using robots and instrumentation specifically designed to prepare and analyse samples have been automated. In addition, increasingly powerful personal computers and workstationsare enabling the development and use of increasingly sophisticated techniques and methods of interpreting instrumental data. So, in some cases, because the instrumentation does more, fewer chemists are required to prepare the sample and measure and interpret the data. On the other hand, the demand for new and increasingly sophisticated analytical techniques, new instrumentation, automation and computerization, and regulatory requirements have opened up new opportunities for analytical chemists in other areas. . In the preparation of this book, it has been the author’s aim to keep in mind not only the requirements of students in this subject but as well the needs of student.
