Microwave-Assisted Sample Preparation for Trace Element Analysis, Second Edition, describes the principles, equipment, and applications involved in sample preparation with microwaves for detecting and analyzing trace elements. Hot topics such as sample preparation for speciation, metabolomics, and halogen determination, as well as the alternatives of sample preparation for special samples (for example, carbon nanotubes, polymers, petroleum products), are also discussed. This completely updated second edition covers all the new devices and more powerful systems that have emerged in the last several years, such as Ultrawave and Ultraclave systems. New challenges in the fields of geology, environmental and biological studies -for example, the need for further determination of rare earth elements and halogens - are currently only covered in scientific journals and not in a comprehensive way. This book offers a summary of the state-of-the-art ways to meet these challenges with microwave-assisted sample preparation.
