Download or read book Fast Liquid Chromatography mass Spectrometry Methods In Food And Environmental Analysis written by Oscar Nunez and published by World Scientific. This book was released on 2015-02-03 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. Whereas the most common approach for solving many analytical problems has often been high-performance liquid chromatography (HPLC), the recent use of fast or ultra-fast chromatographic methods for environmental and food analysis has increased the overall sample throughput and laboratory efficiency without loss (and even with an improvement) in the resolution obtained by conventional HPLC systems.This book brings together researchers at the top of their field from across the world to discuss and analyze recent advances in fast liquid chromatography-mass spectrometry (LC-MS) methods in food and environmental analysis. First, the most novel approaches to achieve fast and ultra-fast methods as well as the use of alternative and complementary stationary phases are described. Then, recent advances in fast LC-MS methods are addressed, focusing on novel treatment procedures coupled with LC-MS, new ionization sources, high-resolution mass spectrometry, and the problematic confirmation and quantification aspects in mass spectrometry. Finally, relevant LC-MS applications in food and environmental analysis such as the analysis of pesticides, mycotoxins, food packaging contaminants, perfluorinated compounds and polyphenolic compounds are described.The scope of the book is intentionally broad and is aimed at worldwide analytical laboratories working in food and environmental applications as well as researchers in universities worldwide.

Other updates include a discussion on fast GC and options for combining GC detectors with mass spectrometry. The section regarding GC Conditions, Derivatization, and Mass Spectral Interpretation of Specific Compound Types has the same number of compound types as the original edition, but the information in each section has been expanded to not only explain some of the spectra but to also explain why certain fragmentations take place. The number of Appendices has been increased from 12 to 17. The Appendix on Atomic Masses and Isotope Abundances has been expanded to provide tools to aid in determination of elemental composition from isotope peak intensity ratios. An appendix with examples on "Steps to follow in the determination of elemental compositions based on isotope peak intensities" has been added. Appendices on whether to use GC/MS or LC/MS, third-party software for use in data analysis, list of information required in reporting GC/MS data, X+1 and X+2 peak relative intensities based on the number of atoms of carbon in an ion, and list of available EI mass spectral databases have been added.

Download or read book Mass Spectra of Flavors and Fragrances of Natural and Synthetic Compounds written by Luigi Mondello and published by John Wiley & Sons. This book was released on 2015-03-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced Component Identification in Complex Mixtures Essential oils are mixtures consisting of monoterpene andsesquiterpene hydrocarbons, their oxygenated derivatives, andaliphatic oxygenated compounds. The difficulties that arise in theGC-MS peak identification of these complex samples is due to thefact that many terpenes have identical mass spectra. This is aconsequence of similarities both in the initial molecule, or in thefragmentation patterns and rearrangements after ionization. Hence,MS identification of these compounds should always be accompaniedby retention time information that may support the MS librarysearch results. This innovative MS library for natural and synthetic products(essential oils, perfumes, etc.) makes the identification ofunknown compounds in complex mixtures easier, faster and morereliable. The use of chromatographic information, such as LinearRetention Index (LRI), can be used to filter MS results, enablingthe more reliable peak assignment of components in complexmixtures. Mass spectra, relative to standard and well-known simple matrixcomponents, were obtained and recorded through GC-MSseparation/identification. Furthermore, traditional informationrelative to each component (CAS number, common name, CAS name,molecular weight, compound formula, chemical class) plus linearretention index values are entered. Flavors and Fragrances of Natural and Synthetic Compounds,3rd edition contains >3000 mass spectra, LRI retentiondata, calculated Kovats RI, and searchable chemical structures ofcompounds of interest for the flavors and fragrances industry.Prepared by the Prof. Luigi Mondello under rigorous measurementconditions, the mass spectral library contains compounds central toflavor and fragrance research.
