Produktbeschreibung

This book focuses on high-throughput analyses for food safety. Because of the contributors domestic and international expertise from industry and government the book appeals to a wider audience. It includes the latest development in rapid screening, with a particular emphasis on the growing use and applicability of a variety of stand-alone mass spectrometry methods as well as using mass spectrometry in hyphenated techniques such as gas chromatograph mass spectrometry (GC-MS) and liquid chromatography mass spectrometry (LC-MS). Readers will be educated to the field of food safety and rapid testing in the most commonly used techniques.
Divided into three parts (Basics of High Throughput Analyses, Mass Spectrometry in High Throughput Analyses, and International Food Safety Testing) this book covers many important aspects of high-throughput analyses for food safety.

Autorenporträt

PERRY G. WANG, PHD, is a research chemist in the Office of Regulatory Science, CFSAN, US FDA. Prior to joining the FDA, Dr. Wang worked in the pharmaceutical and medical device industries. His expertise in the pharmaceutical field focuses on high-throughput drug analysis by LC-MS/MS. His current research at the FDA includes developing analytical methods for chemical ingredients in cosmetics and personal care products by GC-MS/MS and LC-MS/MS. This book is edited in his private capacity but not as an employee of the FDA. MARK F. VITHA, PHD, is a professor at Drake University. He is the editor of The Chemical Analysis Series (Wiley) and the co-editor of Interfaces and Interphases in Analytical Chemistry. In 2011, he was awarded the Windsor Professor of Science and the Ronald D. Troyer Research Fellowship. JOHN F. KAY, PHD, is a chemist and recently retired as the R&D manager at the UK Veterinary Medicines Directorate. For almost 20 years he actively participated in the Codex Alimentarius Committee on Residues of Veterinary Drugs in Food and remains on the JECFA expert roster 2012-2016 for veterinary drug residues. He has held an Honorary Senior Research Fellowship in the Department of Mathematics and Statistics at the University of Strathclyde, Scotland since 2005.
