Planar Chromatography-Mass Spectrometry focuses on a relatively new approach to chemical analysis in general, and to separation science in particular. It is the first book to systemically cover the theoretical background, techniques, instrumentation, and practical applications of planar chromatography-mass spectrometry as a hyphenated tool of analytical chemistry. It also examines the high and as-yet unexploited potential of planar chromatography-mass spectrometry for analytical use in scientific investigations.
This book overviews the combination of planar chromatography, a relatively simple and cost-effective separation step for determining complex mixtures of compounds, with mass spectrometry, an efficient, highly instrumental, and relatively expensive technique that enables rapid identification of separated chemical species. It covers electrophoretic-mass spectrometry methods and applications, which are considered planar chromatographic techniques and are increasingly being exploited in proteomic and molecular biology studies as well as for medical diagnostic purposes. It also provides a selection of applications, such as drug control and forensic and food analysis, including more difficult substances such as carbohydrates and lipids.
The book advocates growth in using planar chromatography-mass spectrometry in laboratories that have appropriate equipment but have not yet employed the techniques in combination. It also describes the use of a relatively inexpensive commercial system that can be adopted by laboratories currently working without the coupled methodology. Aiming to improve power and efficiency when other analytical methods are inadequate, Planar Chromatography-Mass Spectrometry encourages separation science practitioners in academia and industry to combine the two methods for enhanced results.
Explains why modern supercritical fluid chromatography (SFC) is the leading "green" analytical and purification separations technology.
Modern supercritical fluid chromatography (SFC) is the leading method used to analyze and purify chiral and achiral chemical compounds, many of which are pharmaceuticals, pharmaceutical candidates, and natural products including cannabis-related compounds. This book covers current SFC instrumentation as it relates to greater robustness, better reproducibility, and increased analytical sensitivity.
Modern Supercritical Fluid Chromatography: Carbon Dioxide Containing Mobile Phases covers the history, instrumentation, method development and applications of SFC. The authors provided readers with an overview of analytical and preparative SFC equipment, stationary phases, and mobile phase choices. Topics covered include: Milestones of Supercritical Fluid Chromatography; Physical Properties of Supercritical Fluids; Instrumentation for SFC; Detection in SFC; Achiral SFC Method Development; Chiral SFC Method Development; and Preparative Scale SFC. The book also includes highlights of modern applications of SFC in the final chapters--namely pharmaceuticals, consumer products, foods, polymers, petroleum-related mixtures, and cannabis--and discusses the future of SFC.
Provides a clear explanation of the physical and chemical properties of supercritical fluids, which gives the reader a better understanding of the basis for improved performance in SFC compared to HPLC and GC
Describes the advantages of SFC as a green alternative to HPLC and GC for the analysis of both polar, water-soluble, and non-polar analytes
Details both achiral and chiral SFC method development, including modifiers, additives, the impact of temperature and pressure, and stationary phase choices
Details why SFC is the premier modern preparative chromatographic technique used to purify components of mixtures for subsequent uses, both from performance and economic perspectives
Covers numerous detectors, with an emphasis on SFC-MS, SFC-UV, and SFC-ELSD (evaporative light scattering detection)
Describes the application of SFC to numerous high-value application areas
Modern Supercritical Fluid Chromatography: Carbon Dioxide Containing Mobile Phases will be of great interest to professionals, students, and professors involved in analytical, bioanalytical, separations science, medicinal, petroleum, and environmental chemistries. It will also appeal to pharmaceutical scientists, natural-product scientists, food and consumer-products scientists, chemical engineers, and managers in these areas.

Описание: Gas Chromatography: History, Methods and Applications focuses on the main applications of gas chromatography in clinical and forensic toxicology, mainly in the determination of drugs of abuse including the new psychoactive substances in several types of biological matrices. The authors go on to investigated the analysis of gaseous or volatile substances using sensor gas chromatography equipped with a semiconductor gas sensor detector. The simplicity, ease of handling, and high sensitivity of this method allow results to be obtained rapidly, which may provide valuable information for forensic diagnosis. This compilation addresses the way in which food adulteration practices are potentially harmful to human health and so food safety and authenticity constitute an important issue in food chemistry. The chemical composition of foodstuffs is an excellent indicator of quality, origin, authenticity and/or adulteration. The concluding study aims to determine the organic compounds of vinasse through gas chromatography-mass spectrometry GC-MS. Vinasse is a byproduct of ethanol and poses long-term risk to public health because of its persistent and toxic nature.

Описание: Uquid chromatography in the of paper, thin-layer, ion-exchange, and exclusion (gel permeation and gel form filtration) chromatography had not been able to achieve the same success, mainly because of the poor efficiences and the long analysis times arising from the low mobile phase flow rates.
This is the first book that comprehensively and systematically describes the new technology of hydrophilic interaction liquid chromatography (HILIC). Hydrophilic interaction chromatography is a separation technique suitable for polar and hydrophilic compounds and orthogonal to reversed phase liquid chromatography. From small organic molecules to proteins, the text explores the many applications of HILIC in the analytical field. Winner of the President's Award for Excellence, the author explains how HILIC can significantly improve analytical throughput by shortening sample preparation procedure, which is one of the bottlenecks for drug discovery and development in the pharmaceutical industry.
