Book Description
Covering definitions, concepts, and applications, Countercurrent Chromatography recounts the developments in two types of liquid-liquid chromatography termed countercurrent-high-speed countercurrent chromatography (HSCCC) and centrifugal partition chromatography (CPC)-as well as the HSCCC-derived cross-axis CCC, a versatile technique for purification in biotechnology applications. The text investigates mechanisms for mixing liquid phases, particularly hydrostatic techniques for CPC and hydrodynamic for coil planet centrifuges. It also explores the use of countercurrent chromatography in inorganic analysis, chiral separation, and the separation of natural products.

Book Description
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.

Book Description
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

Book Description
Over the past few years, increasing attention has been paid to the search for bioactive compounds from natural sources. The success of plant-derived products such as paclitaxel (Taxol) in tumor therapy or artemisinin in the treatment of malaria has provided the impetus for the introduction of numerous research programmes, especially in Industry. A great deal of effort is being expended in the generation of novel lead molecules of vegetable, marine and microbial origin by the use of high throughput screening protocols. When interesting hits are found, it is essen tial to have methods available for the rapid isolation of target compounds. For this reason, both industry and academia need efficient preparative chromatographic separation techniques and experience in their application. Purified natural products are required for complete spectro scopic identification and full characterization of new compo unds, for biological testing and for the supply of pharmaceuti cals, standards, and starting materials for synthetic work. Obtaining pure products from an extract can be a very long, te dious and expensive undertaking, involving many steps. Sometimes only minute amounts of the desired compounds are at hand and these entities may be labile. Thus it is an advantage to have access to as many different methods as possible in order to aid the isolation process. Although a certain amount of trial and error may be involved, nowadays there is the possibility of devising suitable rapid separation schemes by a judicious choice of the different techniques available.
