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: Reversed-phase high-performance liquid chromatography (RP-HPLC) has become the most widely used method for pharmaceutical analysis, as it ensures accuracy, specificity and reproducibility for the quantification of drugs, while avoiding interference from any of the excipients that are normally present in pharmaceutical dosage forms. This book presents a simple methodology for developing stability-indicating methods and offers a ‘how-to guide’ to creating novel stability-indicating methods using liquid chromatography. It provides the detailed information needed to devise a stability-indicating method for drug substances and drug products that comply with international regulatory guidelines. As such, it is a must-read for anyone engaged in analytical and bioanalytical chemistry: professionals at reference, test, and control laboratories; students and academics at research laboratories, and scientists working for chemical, pharmaceutical, and biotechnology companies.
Описание: High-performance liquid chromatography (HPLC) is increasingly used in the field of traditional Chinese medicine for obtaining fingerprints of Chinese medicinal herbs. This title presents an account of the HPLC technology and fingerprints of commonly-used Chinese herbs.
Описание: There is a growing need for high-throughput separations in food and environmental research that are able to cope with the analysis of a large number of compounds in very complex matrices.

Описание: Evolved gas analysis (EGA) describes analysis of gases or volatile components evolved from a sample undergoing thermal analysis. It is often used in direct combination with chemical analysis techniques such as gas chromatography, IR spectroscopy, or mass spectrometry, and/or with thermogravimetric analysis (TGA), i.e. measuring the change in weight of the sample under controlled conditions. This book focuses on these so-called ""hyphenated techniques"" (EGA-TGA, TGA-GC/MS, etc.), which allow a great deal of chemical information about a sample to be revealed quickly and conveniently.The methods are highly applicable to polymer/plastics samples, but also to other materials including pharmaceuticals, biomass, and various organic and inorganic compounds. Examples of applications related to all these material types are provided in this book.This book provides practical help to anyone interested in the practical aspects of EGA-TGA, including those working in testing laboratories and their clients.
