Micro-X-ray fluorescence offers the possibility for a position- sensitive and non-destructive analysis that can be used for the analysis of non-homogeneous materials and layer systems. This analytical technique has shown a dynamic development in the last 15 years and is used for the analysis of small particles, inclusions, of elemental distributions for a wide range of different applications both in research and quality control. The first experiments were performed on synchrotrons but there is a requirement for laboratory instruments which offers a fast and immediate access for analytical results. The book discuss the main components of a µ-XRF instrument and the different measurement modes, it gives an overview about the various instruments types, considers the special requirements for quantification of non-homogeneous materials and presents a wide range of application for single point and multi-point analysis as well as for distribution analysis in one, two and three dimensions.

Michael Haschke was born 1948, his schooling was combined with teachings for metalworker. After the study of physics at the TU Dresden which was finished 1974 with Ph D he started his career – at first in the Academy of Science of GDR, branch for scientific instrumentation and then in different companies. From the beginning of the 80th he was working in the field of X-Ray analytics. During that time he was responsible for the introduction of energy-dispersive X-Ray spectrometers (EDS) in GDR, for the buildup of the X-Ray product line in Spectro, Kleve including the excitation with polarized radiation, the use of small spectrometers for jewelry analysis and the introduction of poly-capillary based instruments for µ-XRF in Röntgenanalytik Messtechnik Gmb H, Taunusstein in close cooperation with EDAX, USA, the use of µ-XRF as an additional excitation source for electron microscopes in If G, Berlin and finally for the introduction of a complete product line for µ-XRF in Bruker Nano, Gmb H, Berlin. This responsibility was realized as deputy-director or product manager in the different companies. He understood the introduction of new instruments as a combination of the development of the instruments with the introduction into the market. Therefore there is a big experience both for instrumentation as well as for application.
