Countercurrent chromatography (CCC) is a separation technique in which the stationary phase is a liquid. The mobile phase is also a liquid, so biphasic liquid systems with at least two solvents are used. Centrifugal fields are used to hold the liquid stationary phase while pushing the liquid mobile phase through it. This comprehensive reference covers recent advancements in the two types of CCC machines: the high speed CCCs without rotary seals and with coiled spools and centrifugal partition chromatographs (CPC) with rotary seals and interconnected channels. Written by leading international experts in the CCC field, the book focuses on the liquid nature of the stationary phase: giving newcomers the basis to do CCC efficiently and rapidly; explaining the art of obtaining a biphasic liquid system; describing the flow patterns in both CPC and high speed CCC machines; showing possible other uses of a liquid stationary phase; presenting a wealth of applications in the separation of organic, pharmaceutical and inorganic mixtures; and demonstrating that even supercritical fluids can be used in CCC.

Protected designation of origin (PDO) taken together with other geographical indicators, such as protected geographical indication (PGI) and traditional specialty guaranteed (TSG), offer the consumer additional guarantees on the quality and authentication of foods. They are important tools that protect the names of regional foods, such as wines, cheeses, hams, sausages and olives, so that only foods that genuinely originate in a particular region are allowed to be identified as such. The economic value of these regional foods, as well as the increased interest from consumers and the food industry about the traceability and origin of food, mean that it has become necessary to establish methods for PDO and PGI authentication based on the specific characteristics and chemical markers of these kinds of products. This book offers a complete guide of the methods available to authenticate food PDO, beginning with an explanation of the analytical and chemometric methods available for PDO authentication, before looking at the main foods covered, PGI labels and the social and legal framework for food PGIs. It will be of interest to people engaged in the fields of food production, commercialization and consumption, as well as policymakers and control laboratories. Offers a complete guide to the methods available for food Protected Designation of Origin (PDO) authentication Explains the analytical and chemometric methods Focuses on the various food products covered by authentication labels

Applications of Time-of-Flight and Orbitrap Mass Spectrometry in Environmental, Food, Doping, and Forensic Analysis deals with the use of high-resolution mass spectrometry (MS) in the analysis of small organic molecules. Over the past few years, time-of-flight (ToF) and Orbitrap MS have both experienced tremendous growth in a great number of analytical sectors and are now well established in many laboratories where high requirements are placed on analytical performance. This book gives a head-to-head comparison of these two technologies that compete directly with each other. As users with hands-on experience in both techniques, the authors provide a balanced description of the strengths and weaknesses of both techniques. In the vast majority of cases, ToF-MS and Orbitrap-MS have been used for qualitative purposes, mainly identification of discrete molecular entities such as drug metabolites or transformation products of environmental contaminants. This paradigm is now changing as quantitative capabilities are increasingly being explored, as are non-target approaches for unbiased broad-scope screening. In view of the continuous innovation of high-resolution MS instrument manufacturers in designing and developing more powerful machines, technological advances in both hardware and software are considerable, with many novel applications. This book summarizes and analyzes these trends. The compilation of selected examples from diverse analytical fields will allow the readers to discover not only the potential of high-resolution MS in their sector, but also shows advances in other fields that rely on hi-res MS. Provides comprehensive coverage of applications of time-of-flight and orbitrap mass spectrometry in environmental, food, doping, and forensic analysis Explores a variety of specialized techniques, giving a balanced description of the strengths and weaknesses of each Presents a general overview of imaging techniques within analysis
