Sommario/riassunto

Providing an accessible introduction into the use of Total-Reflection X-ray Fluorescence (TXRF) Analysis, both from a theoretical point of view and for practical applications, this new edition of Total-Reflection X-Ray Fluorescence Analysis is completely updated and enlarged to emphasize new methods and techniques. Written to enable students and scientists to evaluate the suitability of a TXRF method for their specific needs, the text provides an overview to the physical fundamentals and principles of Total-Reflection X-ray Fluorescence (TXRF) Analysis, explains instrumentation and setups, and
