Nowadays, there is a growing need for applications in food control and safety analysis to cope with the analysis of a large number of analytes in a very complex matrix. New analytical procedures are demanding sensitivity, robustness, effectiveness and high resolution within a reduced analysis time. Most of these requirements may be met to a certain extent by the total or partial automation of the conventional analytical methods, including sample preparation or sample pre-treatment coupled on-line to an analytical system. Despite the advances in chromatographic separations and mass spectrometry techniques, sample preparation is still one of the most important parts in any analytical method development and an effective sample preparation is essential for achieving good analytical results. Obviously, ideal sample preparation methods should be fast, accurate, precise and must keep sample integrity. For this reason, and over the last years, considerable efforts have been made to develop modern approaches in sample treatment techniques that enable the reduction of the analysis time without compromising the integrity of the extraction process. The aim of this book is to discuss new trends in sample preparation techniques applied to food analysis, and it will address not only the principles of each technique, but the most relevant applications in food control and safety analysis published over the few last years.

One of the most important challenges in modernfood analysis is the research of new reliable sample preparationmethods. In fact, traditional and automated procedurescan ensure reliable results on condition that sample pretreatmentmethods are fast, accurate, precise, and able to maintainthe integrity of extraction processes. The book New trends insample preparation techniques for food analysis, editedby Oscar N��ez and Paolo Lucci, describes the currentstate of art of sample pretreatment systems in the fieldof food analysis.Contents The book is subdivided into seven chapters with afive-page detailed preface providing a preliminary discussionabout extraction procedures. The first chapter concerns newtrends in solid-phase extraction (SPE) analyses and innovativesorbent chemicals. The book considers new molecularlyimprinted polymers for SPE systems in Chap. 2, with relationto synthetic processes and practical examples. Chapter 3 isdedicated to turbulent flow chromatography and related applicationsfor food analyses (trace elements, contaminants).Subsequently, the discussion concerns new analytical applicationsfor food matrices: QuEChERS (Chap. 4) andmicroextraction methods for simple and inexpensive separations(Chap. 5). Chapter 6 is completely dedicated toionic liquids as an essential component of sample preparationfor the determination of metals and organicchemicals in food matrices. The final chapter discussesthe current state of art of supercritical fluid extractionfor different analytical purposes.

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. 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. The contributions are organized to reflect the way in which analytical chemists approach a problem. It is intended for a broad audience of analytical chemists, both educators and practitioners of the art and can assist in the preparation of courses as well in the selection of sampling and sample preparation techniques to address the challenges at hand. Above all, it is designed to be helpful in learning more about these topics, as well as to encourage an interest in sampling and sample preparation by outlining the present practice of the technology and by indicating research opportunities. Sampling and Sample preparation is a large and well-defined field in Analytical Chemistry, relevant for many application areas such as medicine, environmental science, biochemistry, pharmacology, geology, and food science. This work covers all these aspects and will be extremely useful to researchers and students, who can use it as a starting point to design and implement their experiments and for quality-reviewed background information There are limited resources that Educators can use to effectively teach the fundamental aspects of modern sample preparation technology. Comprehensive Sampling and Sample Preparation addresses this need, but focuses on the common principles of new developments in extraction technologies rather than the differences between techniques thus facilitating a more thorough understanding Provides a complete overview of the field. Not only will help to save time, it will also help to make correct assessments and avoid costly mistakes in sampling in the process Sample and sample preparation are integral parts of the analytical process but are often less considered and sometimes even completely disregarded in the available literature. To fill this gap, leading scientists have contributed 130 chapters, organized in 4 volumes, covering all modern aspects of sampling and liquid, solid phase and membrane extractions, as well as the challenges associated with different types of matrices in relevant application areas

The importance of accurate sample preparation techniques cannot be overstated--meticulous sample preparation is essential. Often overlooked, it is the midway point where the analytes from the sample matrix are transformed so they are suitable for analysis. Even the best analytical techniques cannot rectify problems generated by sloppy sample pretreatment. Devoted entirely to teaching and reinforcing these necessary pretreatment steps, Sample Preparation Techniques in Analytical Chemistry addresses diverse aspects of this important measurement step. These include: * State-of-the-art extraction techniques for organic and inorganic analytes * Sample preparation in biological measurements * Sample pretreatment in microscopy * Surface enhancement as a sample preparation tool in Raman and IR spectroscopy * Sample concentration and clean-up methods * Quality control steps Designed to serve as a text in an undergraduate or graduate level curriculum, Sample Preparation Techniques in Analytical Chemistry also provides an invaluable reference tool for analytical chemists in the chemical, biological, pharmaceutical, environmental, and materials sciences.
