Book Description
This informative book offers a wide range of knowledge on the technologies and applications of the cutting-edge field of high-resolution mass spectrometry (HRMS) in different areas of analysis. HRMS has changed the nature of experimentation and investigation in so many analytical realms. Determining exact mass determination, high resolution, and specificity—via the special features provided by HRMS instruments—is now possible for determining the composition of the analyte of interest, both qualitatively and quantitatively. High-Resolution Mass Spectrometry and Its Diverse Applications: Cutting-Edge Techniques and Instrumentation begins with an overview of the basic instrumentation techniques and goes on to present research on diverse new uses of HRMS in clinical testing, such as for therapeutic drug designing, discovery, and development; in forensic studies and investigations; in quality management systems; for analysis of pesticides; for analysis of single cells; in analysis of fossil fuels; for use in space and planetary science; and more. Chapters relay how HRMS plays an important role in the structure elucidation and unknown determination in many fields and is a great measure to be used for quantitative analyses. The book considers how these properties make the technique a strong aid in many areas. This volume highlights how HRMS can be a useful tool for scientists and researchers, faculty and students, and industry professionals in many scientific areas of study.

Book Description
Gradient elution demystified Of the various ways in which chromatography is applied today, few have been as misunderstood as the technique of gradient elution, which presents many challenges compared to isocratic separation. When properly explained, however, gradient elution can be less difficult to understand and much easier to use than often assumed. Written by two well-known authorities in liquid chromatography, High-Performance Gradient Elution: The Practical Application of the Linear-Solvent-Strength Model takes the mystery out of the practice of gradient elution and helps remove barriers to the practical application of this important separation technique. The book presents a systematic approach to the current understanding of gradient elution, describing theory, methodology, and applications across many of the fields that use liquid chromatography as a primary analytical tool. This up-to-date, practical, and comprehensive treatment of gradient elution: * Provides specific, step-by-step recommendations for developing a gradient separation for any sample * Describes the best approach for troubleshooting problems with gradient methods * Guides the reader on the equipment used for gradient elution * Lists which conditions should be varied first during method development, and explains how to interpret scouting gradients * Explains how to avoid problems in transferring gradient methods With a focus on the use of linear solvent strength (LSS) theory for predicting gradient LC behavior and separations by reversed-phase HPLC, High-Performance Gradient Elution gives every chromatographer access to this useful tool.

Abstract: This dissertation reports the development of novel, fully automatable, online multidimensional liquid chromatography (MDLC) technologies and methodologies to accelerate proteomics and glycomics mapping from complex biological samples. Chapter 2 reports the development of an online two-dimensional (2D) liquid chromatography (LC) system-with separations based on hydrophilic interactions in the first dimension and low-pH reversed-phase (RP) separation (peptide hydrophobicity) in the second-that operated with high resolution and orthogonality. This hydrophilic interaction liquid chromatography (HILIC) -RP platform featured an RP trap column plus a mixing loop before the first dimension to facilitate direct aqueous sample loading; an additional sample loop plus a strong cation exchange (SCX) trap column was implemented to circumvent the problem of solvent incompatibility between the two columns. The performance of this system was benchmarked through analysis of the proteome of Saccharomyces cerevisiae, resulting in the identification of more than 2000 proteins with abundances spanning from 40 to 〖10〗 DEGREES6 copies/cell. Chapter 3 reports a novel online three-dimensional (3D) HILIC-SCX-RP coupled with porous graphitic carbon (PGC) LC platform derived from the HILIC-RP design, featuring additional SCX fractionations, operating through a charge-centric separation mechanism, to extend the separation efficiency and platform orthogonality; the PGC column was integrated to recapture non-retained hydrophilic analytes for concomitant analyses of both hydrophilic and hydrophobic analytes within the same sample injection event. This integrated technology exhibited superior performance for the proteomics analyses of the total lysate of primary cerebellar granule neurons (CGNs) and cynomolgus monkey brain tissue, with enhanced protein and proteome coverage. One of the most comprehensive CGNs proteome to date was characterized: in total, 2201 proteins and 16,937 unique peptides. This 3D HILIC-SCX-RP/PGC system allowed the first detailed and simultaneous N-glycomics and N-glycoproteomics analyses of cynomolgus monkey plasma, establishing a glycan library containing 122 proposed N-glycans with confirmed complementary sites of N-glycosylation; 38 N-glycolylneuraminic acid (NeuGc)-containing N-glycans were also verified through tandem mass spectrometry for the first time. Finally, Chapter 4 describes the first online 2D PGC-RP LC system with dual sample traps that allowed the implementation of shotgun proteomics and glycomics analyses using less-sophisticated instrumentation. The PGC-platform operated through a mixed mode of mechanisms for peptide separation, taking advantage of both planar contact area-based interactions and hydrophobicity, allowing elimination of the aforementioned RP trap column, mixing loop, and related switching valves for sample loading; thus, this system could be readily assembled on a commercially available MDLC system with minimal modifications. The dual-trap column configuration was adopted, offering desirable high-throughput with almost no idle time for sample fractionation, trapping, or desalting. This 2D PGC-RP technology performed well, as judged by the results of proteomics and glycoproteomics analyses of cerebellar granule neurons lysates and cynomolgus monkey plasma. A comparison of the HILIC-SCX-RP and PGC-RP analyses in
