Analysis of Pesticide in Tea: Chromatography-Mass Spectrometry Methodology is a comprehensive book, providing serial, rapid, high-throughput analytical methods for determining more than 600 pesticides in tea. There are increasing numbers of strict limit standards for pesticide residues in edible agricultural products in countries all over the world. The threshold for pesticide residues in tea is high for international trade. At present, 17 countries and international organizations have stipulated MRL levels for over 800 pesticide residues in tea. All methods described in this book are validated by an independent, U.S.-based organization (AOAC International), and all indexes have satisfied AOAC International's criteria. China has a history of 5000 years in growing tea and is a large tea producer with 80 million people involved in tea growing. China exports tea to over 100 countries worldwide, enjoying a high reputation for quality and variety. - Covers a wide range of research activities that are highly appropriate to current research methods - Reflects the most recent research in nearly all cases, providing an excellent compilation of feasible methods needed for official analysis - Describes methods that are internationally validated by an independent, U.S.-based organization (AOAC International) - Authored by Dr. Pang, who is internationally recognized in the area of pesticide residues and other contaminants in foods

This book explores different aspects of LA-ICP-MS (laser ablation-inductively coupled plasma-mass spectrometry). It presents a large array of new analytical protocols for elemental or isotope analysis. LA-ICP-MS is a powerful tool that combines a sampling device able to remove very small quantities of material without leaving visible damage at the surface of an object. Furthermore, it functions as a sensitive analytical instrument that measures, within a few seconds, a wide range of isotopes in inorganic samples. Determining the elemental or the isotopic composition of ancient material is essential to address questions related to ancient technology or provenance and therefore aids archaeologists in reconstructing exchange networks for goods, people and ideas. Recent improvements of LA-ICP-MS have opened new avenues of research that are explored in this volume.

Hyphenations of Capillary Chromatography with Mass Spectrometry provides comprehensive coverage of capillary chromatography with mass spectrometry—both single and multidimensional approaches. The book examines nearly all capillary chromatography approaches, combined with a variety of MS forms, giving readers a wide and detailed view on current-day analytical strategies and applications. Of particular focus are novel developments in the field of MS, such as the Orbitrap, HR ToF, ToF MS with variable electron-impact energy, fast MS-MS and APGC technology. Junior scientists conducting research on mono-dimensional chromatography-MS fundamental relationships and experienced analytical chemists working in conventional capillary chromatography and classical multidimensional chromatography will find this an ideal application-based reference on the hyphenations of these domains. Combines mass spectrometry with a range of chromatographic approaches Emphasizes the importance of both capillary chromatography and mass spectrometry methods, thus stimulating separation scientists to fully exploit both analytical dimensions Authored by two of the world’s leading analytical chemists who have a total of more than 40 years of experience in research and instruction

This book provides a cutting-edge scientific overview of Chinese liquor, also known as Baijiu. Chinese liquor is one of the world’s most ancient fermented alcoholic beverages. Fermented foods and beverages are consumed worldwide as an indispensable constituent in our daily life. However, most fermented foods rely on traditional techniques with limited known scientific knowledge. These indigenous processes are typically empirical without scientifically-based control and technological insights. The book analyses Chinese liquor processing on the three most important disciplines of fermented foods: process technology/engineering, flavor chemistry, and microbiology. It also addresses the perspectives and future research needs associated with spontaneous fermented foods. This book offers a deep understanding of the science of Chinese liquor production to students, researchers, and related practitioners both in the academic and the industry. It would also benefit many other fields of fermented foods for their optimization, standardization, and modernization.
