This book was released on 2016-12-08 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis addresses the evolving field of measurement science, specifically that of mass spectrometry (MS) and ion mobility spectrometry (IMS) based techniques. It focuses on the design, construction and implementation of low-cost, easy-to-manufacture measurement tools that are used in modern settings such as airport security screening. Advances in these technologies often involve minimal performance enhancement at ever-increasing cost, which in turn limits accessibility to versatile measurement tools. This problem is addressed using desktop 3D printers along with widely available materials for the production of novel ion lenses and an IMS instrument with a performance comparable to that of many commercial systems. Baird ́s findings are a source of inspiration for scientists exploring this emerging field./div

Download or read book Mass Spectrometry Imaging in Food Analysis written by Leo M.L. Nollet and published by CRC Press. This book was released on 2020-04-29 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food contains various compounds and many technologies exist to analyze those molecules of interest. However, the analysis of the spatial distribution of those compounds using conventional technology, such as liquid chromatography-mass spectrometry or gas chromatography-mass spectrometry is difficult. Mass spectrometry imaging (MSI) is a mass spectrometry technique to visualize the spatial distribution of molecules, as biomarkers, metabolites, peptides or proteins by their molecular masses. Despite the fact that MSI has been generally considered a qualitative method, the signal generated by this technique is proportional to the relative abundance of the analyte and so quantification is possible. Mass Spectrometry Imaging in Food Analysis, a volume in the Food Analysis and Properties Series, explains how the novel use of matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) will be an ideal complementary approach. MALDI-MSI is a two-dimensional MALDI-MS technology that can detect compounds in a tissue section without extraction, purification, separation, or labeling. It can be used to visualize the spatial distribution of biomolecules in foods. Features: Explains the novel use of matrix-assisted laser desorption/ionization mass spectrometry imaging in food analysis Describes how MALDI-MSI will be a useful technique for optical quality assurance. Shows how MALDI-MSI detects food contaminants and residues Covers the historical development of the technology While there are a multitude of books on mass spectrometry, none focus on food applications and thus this book is ideally suited to food scientists, food industry personnel engaged in product development, research institutions, and universities active in food analysis or chemical analysis.

Download or read book The Encyclopedia of Mass Spectrometry written by Michael L. Gross and published by Elsevier Science. This book was released on 2006-12-21 with total page 1040 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 6: Ionization Methods captures the story of molecular ionization and its phenomenal evolution that makes mass spectrometry the powerful method it is today. Chapters 1 and 2 cover fundamentals and various issues that are common to all ionization (e.g., accurate mass, isotope clusters, and derivatization). Chapters 3-9 acknowledge that some ionization methods are appropriate for gas-phase molecules and others for molecules that are in the solid or liquid states. Chapters 3-6 cover gas-phase molecules, dividing the subject into: (1) ionization of gas-phase molecules by particles (e.g., EI), (2) ionization by photons, (3) ionization by ion-molecule and molecule-molecule reactions (e.g., APCI and DART), and ionization in Strong electric fields (i.e., Electrohydrodynamic and Field Ionization/Desorption). "Ionization in a Strong Electric Field" illustrates the transition to ionization of molecules in the solid or liquid states, covered in Chapters 7-9: (1) spray methods for ionization (e.g., electrospray), (2) desorption ionization by particle bombardment (e.g., FAB), and (3) desorption by photons (e.g., MALDI). Electrospray and MALDI also lead to applications in biophysical chemistry, the theme of Chapter 10. Chapter 11 reconsiders ionization from the view of choosing an ionization method. The range of subjects is from ionization of organic and biomolecules to the study of microorganisms.

This book was released on 2018-05-03 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pseudomonas aeruginosa and Acinetobacter baumannii are among the most common non-lactose-fermenting Gram-negative pathogens responsible for hospital-acquired infections, especially in intensive care units (ICUs). The treatment of infections caused by these bacteria is complicated due to the emergence of multi-drug resistance as the two species are noted for their intrinsic resistance to antimicrobial agents and their ability to acquire genetic elements that encode for resistance determinants. In both species, resistance to multiple classes of antimicrobial agents can seriously compromise the ability to treat infected patients, especially the immunocompromised. Consequently, very few antimicrobials remain as treatment options. Mechanisms of resistance in both of these pathogens include the production of β-lactamases and aminoglycoside-modifying enzymes as well as reduced or lack of expression of outer membrane proteins, mutations in topoisomerases, and up-regulation of efflux pumps. To that purpose, the findings of the studies included in this book deal with the prevalence of resistant isolates to various antimicrobial agents in both P. aeruginosa and A. baumannii, their underlying mechanisms of resistance, their virulence factors, their pathogenesis, and prospective treatment options. Special thanks are due to Mr. Bassam El-Hafi for facilitating procedures involved in this publication.
