This book covers one of the most important areas in analytical sciences, i.e. that of extraction techniques for organic compounds in environmental and related matrices, e.g. food. This text discusses all of the key stages for analysing a sample for organic compounds from the initial sampling protocols through to the range of different extraction techniques used for solid, liquid and air samples and finally through to the final chromatographic analysis. The text provides detailed information on specific extraction techniques to prepare samples for organic compound analysis.

The topics covered include the following:

• Initial steps for solid, aqueous and air sampling.
• Extraction techniques for aqueous samples, including LLE, purge and trap, SPE, SPME, SBSE, SDME, membrane microextraction and MEPS.
• Extraction techniques for solid samples, including Soxhlet, "Soxtec", shake-flask, sonication, PFE, MAE, SFE and MSPD.
• Extraction techniques for air sampling, including whole air, enrichment approaches and desorption techniques.
• Pre-concentration approaches for post-extraction.
• Practical aspects for chromatographic analysis (GC and HPLC) of organic compounds.
• Quality assurance aspects of analysis.
• Health and safety considerations.

Key features include the following:

• Up-to-date information on the latest development in extraction techniques for organic compounds in environmental and food matrices.
• Written in the AnTS style, it is ideal for use as a self-study guide, as the basis of a taught course or guided reading for new "early-career" researchers.
• Includes a resources section to guide the reader to other sources of information.

Extraction Techniques in Analytical Sciences should prove invaluable to students who are studying university-level courses – "undergraduate- to postgraduate-taught". The text will also prove invaluable as a key starting point for individuals undertaking applied research in the fields of analytical, bioanalytical, environmental and food sciences.

The Analytical Techniques in the Sciences series of books provides coverage of all of the major analytical techniques and their application in the most important areas of physical, life and material sciences. Each text is presented in an open learning/distance learning style, in which the learning objectives are clearly identified. The reader's understanding of the material is constantly evaluated by the use of self-assessment and discussion questions. Series Editor: David J. Ando
