In particular, sections have been added on microplasmas and new types of spectrometers, while that on the rapidly expanding field of speciations with practical examples from life and environmental sciences have been included. Still in one handy volume, the book covers all the important modern aspects of atomic fluorescence, emission and absorption spectroscopy as well as plasma mass spectroscopy in a readily comprehensible and practice-oriented manner. A thorough explanation of the physical, theoretical and technical basics, example applications including the concrete execution of analysis and comprehensive cross-references to the latest literature allow even newcomers easy access to the methodologies described.
