Sample treatment has been the focus of intensive research in the last 20 years since it still remains a bottleneck in precise analytical procedures. The low concentration of the target analytes, the large amount of potential interfering agents and the incompatibility of the sample matrix with the instrumental techniques are the main reasons for these bottlenecks. In most of these methods, sample treatment is an unavoidable step and it has a clear influence on the quality (sensitivity, selectivity, and accuracy) of the final analytical results. While the usefulness of microextraction techniques has been established, their complete acceptance in analytical laboratories (including official methods of analysis) depends on their successful automation and integration with conventional analytical instrumentation. Analytical Microextraction Techniques presents comprehensive information about several analytical methods that are useful in the laboratory. These include: sorptive microextraction, solid and liquid phase microextraction, packed sorbent microextraction, miniaturized dispersive solid-phase extraction, thin film and nanoparticle based techniques, and membrane-based techniques. This is a vital reference on microextraction and sample preparation techniques for applied chemistry students, analytical chemists and laboratory technicians.

This book presents detailed descriptions of the most relevant sorbent based and solvent-based microextraction techniques. The development of such miniaturised techniques is an important focus area in Green Analytical Chemistry as it allows for the reduction of toxic solvents and hazardous substances and decreases the complexity, cost, and time of analytical procedures. Numerous advances have been made in this field, and currently, there are a great number of microextraction techniques thanks to the development of novel materials such as nanomaterials and green solvents. This book provides an overview of the two main groups of microextractions, sorbent-based, and solvent-based. Each chapter focuses on the description of the technique fundamentals, the main applications, and the novel developments carried out in recent years written by a renowned expert or group of experts in the field. The main audience will be graduates, postgraduates, and researchers. It is also a useful resource for Master and Ph.D. students that are working in the development of sustainable extraction techniques

The relatively new technique of solid phase microextraction (SPME) is an important tool to prepare samples both in the lab and on-site. SPME is a "green" technology because it eliminates organic solvents from analytical laboratory and can be used in environmental, food and fragrance, and forensic and drug analysis. This handbook offers a thorough background of the theory and practical implementation of SPME. SPME protocols are presented outlining each stage of the method and providing useful tips and potential pitfalls. In addition, devices and fiber coatings, automated SPME systems, SPME method development, and In Vivo applications are discussed. This handbook is essential for its discussion of the latest SPME developments as well as its in depth information on the history, theory, and practical application of the method. Practical application of Solid Phase Microextraction methods including detailed steps Provides history of extraction methods to better understand the process Suitable for all levels, from beginning student to experienced practitioner

Analysis imposes substantial challenges, especially when dealing with analytes present at trace levels in complex matrices. Although modern instrumentation has simplified analyses and makes them more reliable, its use is only the last step of the whole analytical process. On the other hand, sample preparation still represents the bottleneck in many analytical methods and often requires the use of extensive protocols before instrumental analysis. Solid-phase microextraction (SPME) is a well-established sample-prep technique for simultaneous extraction and pre-concentration of compounds from a variety of matrices. Given its compliance with the principles of green analytical chemistry, as well as the simplicity, versatility, and availability of different formats, SPME addresses several challenges associated with the traditional sample preparation approaches and allows for a substantial streamlining of the analytical workflow. This book is the reprint of a Special Issue that includes six contributions provided by some of the world's leading research groups in the field and focuses on recent advances in solid-phase microextraction.
