Book Synopsis Multiresidue Methods for the Analysis of Pesticide Residues in Food by : Horacio Heinzen

Download or read book Multiresidue Methods for the Analysis of Pesticide Residues in Food written by Horacio Heinzen. This book was released on 2017-10-10. Available in PDF, EPUB and Kindle. Book excerpt: In the last decades the public concern on the pesticide residues content in foods have been steadily rising. The global development of food trade implies that aliments from everywhere in the world can reach the consumer`s table. Therefore, the identification of agricultural practices that employ different pesticides combinations and application rates to protect produce must be characterized, as they left residues that could be noxious to human health. However, the possible number of pesticides (and its metabolites of toxicological relevance) to be found in a specific commodity is almost 1500, and the time needed to analyze them one by one, makes this analytical strategy a unrealistic task. To overcome this problem, the concept of Multi Residue Methods (MRM) for the analysis of pesticide traces have been developed. The advent of new and highly sensitive instrumentation, based in hyphenatedchromatographic systems to coupled mass analyzers (XC (MS/MS) or MSn) permitted simultaneously the identification and the determination of up to hundreds of pesticide residues in a single chromatographic run. Multiresidue Methods for the Analysis of Pesticide Residues in Food presents the analytical procedures developed in the literature, as well as those currently employed in the most advanced laboratories that perform routinely Pesticide Residue Analysis in foods. In addition to these points, the regulations, guidelines and recommendations from the most important regulatory agencies of the world on the topic will be commented and contrasted.

Book Synopsis Liquid Chromatography by : F. Hernández

Download or read book Liquid Chromatography written by F. Hernández. This book was released on 2013-01-08. Available in PDF, EPUB and Kindle. Book excerpt: Pesticide residue analysis is a specialized field of modern analytical chemistry, where the role of LC–MS is of great importance. A highly reliable determination, including both quantification and identification, of pesticide residues in food is required nowadays because of the strict international regulations on maximum residue Limits. The increasing interest of including metabolites in analyses comes from the inclusion of pesticide-related compounds within the residue definition. The polar character of most pesticides used at present and their metabolites make LC coupled to tandem MS the technique of choice for the great majority of compounds. Thus, LC–MS/MS with a triple-quadrupole (QqQ) analyzer is highly appropriate for developing multiresidue methods, where up to 200–300 analytes can be simultaneously determined. It can also be efficiently applied to solve analytical problems associated with some problematic pesticides, such as those present as ionic compounds in the samples, which have to be determined with more specific LC–MS/MS methods. High-resolution MS using modern analyzers like time of flight or Orbitrap offers interesting features for wide-scope screening of pesticides and metabolites in food, due to their mass accuracy capabilities, with the advantage that a retrospective analysis is feasible at any time to search for other compounds that were not included in the first analysis.

Book Synopsis Applications in High Resolution Mass Spectrometry by : Roberto Romero-González

Download or read book Applications in High Resolution Mass Spectrometry written by Roberto Romero-González. This book was released on 2017-03-07. Available in PDF, EPUB and Kindle. Book excerpt: Applications of High Resolution Mass Spectrometry: Food Safety and Pesticide Residue Analysis is the first book to offer complete coverage of all aspects of high resolution mass spectrometry (HRMS) used for the analysis of pesticide residue in food. Aimed at researchers and graduate students in food safety, toxicology, and analytical chemistry, the book equips readers with foundational knowledge of HRMS, including established and state-of-the-art principles and analysis strategies. Additionally, it provides a roadmap for implementation, including discussions of the latest instrumentation and software available. Detailed coverage is given to the application of HRMS coupled to ultra high-performance liquid chromatography (UHPLC-HRMS) in the analysis of pesticide residue in fruits and vegetables and food from animal origin. The book also discusses extraction procedures and the challenges of sample preparation, gas chromatography coupled to high resolution mass spectrometry, flow injection-HRMS, ambient ionization, and identification of pesticide transformation products in food. Responding to the fast development and application of these new procedures, this book is an essential resource in the food safety field. Arms researchers with an in-depth resource devoted to the rapid advances in HRMS tools and strategies for pesticide residue analysis in food Provides a complete overview of analytical methodologies and applications of HRMS, including UHPLC-HRMS, HRMS coupled with time of flight (TOF) and/or GC-Orbitrap, and flow injection-HRMS Discusses the current international regulations and legislation related to the use of HRMS in pesticide residue analysis Features a chapter on the hardware and software available for HRMS implementation Offers separate chapters on HRMS applied to pesticide residue analysis in fruits and vegetables and in food from animal origin
