The level and scope of the book is designed for those working with AES: for technicians (operators), graduate students and researchers. Therefore, the emphasis is on guiding the user to optimize his/her work with AES. After a short introduction, the technique is presented step by step in a logical sequence, from sample preparation and instrument setup through data acquisition to data evaluation. Guidance to problem solving and a number of typical, worked examples facilitate quick access to sufficient expertise to acquire, treat and judge AES data in a reliable manner. The book will thus be invaluable, not only to the practical analyst, but also to the scientific supervisor and laboratory manager.
