Comprehensive Sampling and Sample Preparation is a complete treatment of the theory and methodology of sampling in all physical phases and the theory of sample preparation for all major extraction techniques. It is the perfect starting point for researchers and students to design and implement their experiments and support those experiments with quality-reviewed background information. Now in its second edition, this resource provides the latest knowledge and technologies in the field. In its four volumes, fundamentals of sampling and sample preparation are reinforced through broad and detailed sections dealing with Biological and Medical, Environmental and Forensic, and Food and Beverage applications. Emerging areas in the field are discussed in-depth and contributions are organized to reflect the way in which analytical chemists approach a problem. The latest edition includes updated chapters along with new chapters on exciting topics including micro- and nano extractions, green solvents, nanomaterials and nanocomposites in extraction studies, and solid-phase extractions. This work will appeal to a broad audience of analytical chemists. It will also assist educators and practitioners in the preparation of courses and to spark students’ interest in sampling and sample preparation.
