München, den 25.04.2017 …………………………………………………………………………………………Scarlet Beck Dissertation eingereicht am 23.09.2016 1. Gutachter: Prof. Dr. Matthias Mann 2. Gutachter: Prof. Dr. Jürgen Cox Mündliche Prüfung am 04.11.2016 iii iv ABSTRACT Mass spectrometry (MS)-based proteomics has become a powerful technology for the identification and quantification of thousands of proteins. However, the coverage of complete proteomes is still very challenging due to the high sample complexity and the difference in protein concentrations. In data-dependent shotgun proteomics several peptides elute simultaneously from the column and are isolated by the quadrupole and fragmented by the collision cell one at a time. This method has two major disadvantages. On the one hand, a large number of eluting peptides cannot be targeted since the sequencing speeds of current instruments are too slow and on the other hand, peptides that only differ slightly in mass and elute together are co-isolated and co-fragmented, resulting in chimeric MS2 spectra. Therefore an urgent need for further developments and improvements of mass spectrometers remains. The aim of this thesis was to co-develop, evaluate and improve novel quadrupole time-of-flight (QTOF) mass spectrometers. In my first project I have described the developments and improvements of the hardware of the high-resolution QTOF mass spectrometer, the impact II, and have shown that this instrument can be used for very deep coverage of diverse proteomes as well as for accurate and reproducible quantification. -
Portable Mass Spectrometry
Food Analytical Methods https://doi.org/10.1007/s12161-019-01666-6 Potential of Recent Ambient Ionization Techniques for Future Food Contaminant Analysis Using (Trans)Portable Mass Spectrometry Marco H. Blokland1 & Arjen Gerssen1 & Paul W. Zoontjes1 & Janusz Pawliszyn2 & Michel W.F. Nielen1,3 Received: 3 June 2019 /Accepted: 31 October 2019 # The Author(s) 2019 Abstract In food analysis, a trend towards on-site testing of quality and safety parameters is emerging. So far, on-site testing has been mainly explored by miniaturized optical spectroscopy and ligand-binding assay approaches such as lateral flow immunoassays and biosensors. However, for the analysis of multiple parameters at regulatory levels, mass spectrometry (MS) is the method of choice in food testing laboratories. Thanks to recent developments in ambient ionization and upcoming miniaturization of mass analyzers, (trans)portable mass spectrometry may be added to the toolkit for on-site testing and eventually compete with multiplex immunoassays in mixture analysis. In this study, we preliminary evaluated a selection of recent ambient ionization techniques for their potential in simplified testing of selected food contaminants such as pesticides, veterinary drugs, and natural toxins, aiming for a minimum in sample preparation while maintaining acceptable sensitivity and robustness. Matrix-assisted inlet ionization (MAI), handheld desorption atmospheric pressure chemical ionization (DAPCI), transmission-mode direct analysis in real time (TM-DART), and coated blade spray (CBS) were coupled to both benchtop Orbitrap and compact quad- rupole single-stage mass analyzers, while CBS was also briefly studied on a benchtop triple-quadrupole MS. From the results, it can be concluded that for solid and liquid sample transmission configurations provide the highest sensitivity while upon addition ofastationaryphase,suchasinCBS,evenlowμg/L levels in urine samples can be achieved provided the additional selectivity of tandem mass spectrometry is exploited. -

PARSING AND ANALYSIS OF MASS SPECTROMETRY DATA OF COMPLEX BIOLOGICAL AND ENVIRONMENTAL MIXTURES by Kevin Kovalchik B.S., Oregon State University, 2014 B.M., The University of Idaho, 2007 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (CHEMISTRY) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) August 2019 © Kevin Kovalchik, 2019 The following individuals certify that they have read, and recommend to the Faculty of Graduate and Postdoctoral Studies for acceptance, the dissertation entitled: PARSING AND ANALYSIS OF MASS SPECTROMETRY DATA OF COMPLEX BIOLOGICAL AND ENVIRONMENTAL MIXTURES submitted by Kevin A Kovalchik in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Chemistry Examining Committee: David DY Chen Co-supervisor John V Headley Co-supervisor Roman Krems Supervisory Committee Member Ed Grant University Examiner Keng Chou University Examiner ii Abstract The chemical characterization of biological and environmental samples are areas of research which involve the analysis of highly complex chemical mixtures. While the samples from these two fields differ greatly in composition, they present similar challenges. Complex mixtures provide a challenge to the analytical chemist as compounds in the mixture can have matrix effects which interfere with the analysis. Indeed, these interfering compounds may even be analytes themselves. High resolution mass spectrometry, which separates and detects ions based on their mass-to-charge ratio, is a powerful tool in the analysis of such mixtures. The amount of data resulting from such analyses, however, can be intractable to manual analysis, necessitating the use of computational tools. -
CHEMISTRY Life in an RNA World
wint'00.html Vol. I U · C H E M I S T R Y Life in an RNA World by Donald H. Burke, Assistant Professor of Chemistry Donald Burke joined the chemistry department as an assistant professor after receiving a PhD at the University of Califormia, Berkeley, and postdoctoral studies at the University of Colorado. We are indebted to him for this summary of the ongoing efforts in his and others' laborotories in this exciting research area. The Editors RNA-based life? It is the sort of thing they might have used on Star Trek, if they could have found a way to work it into the plot. They had creatures made from gigantic crystals, swarms of microscopic robots with a collective consciousness, and creatures that floated through outer space. Vulcan biochemistry was different enough that it used copper in place of iron to carry oxygen. Why not a cellular life form devoid of proteins, that used RNA molecules to perform catalysis and maintain genetic information? For the most part, if a macromolecule is doing work in a cell here on earth, that molecule is a protein, with a few notable, but isolated exceptions. Does it have to be that way? Can RNA replace proteins or even repair metabolic damage wrought by proteins that misbehave? The question lies at the heart of some avenues of biomedical and microbial engineering, and the answer may reveal much about the earliest forms of life on earth. The last four decades have seen a steady shift in the perception of RNA's role in biology. -

1 Introduction of Mass Spectrometry and Ambient Ionization Techniques
1 1 Introduction of Mass Spectrometry and Ambient Ionization Techniques Yiyang Dong, Jiahui Liu, and Tianyang Guo College of Life Science & Technology, Beijing University of Chemical Technology, No. 15 Beisanhuan East Road, Chaoyang District, Beijing, 100029, China 1.1 Evolution of Analytical Chemistry and Its Challenges in the Twenty-First Century The Chemical Revolution began in the eighteenth century, with the work of French chemist Antoine Lavoisier (1743–1794) representing a fundamental watershed that separated the “modern chemistry” era from the “protochemistry” era (Figure 1.1). However, analytical chemistry, a subdiscipline of chemistry, is an ancient science and its metrological tools, basic applications, and analytical processes can be dated back to early recorded history [1]. In chronological spans covering ancient times, the middle ages, the era of the nineteenth century, and the three chemical revolutionary periods, analytical chemistry has successfully evolved from the verge of the nineteenth century to modern and contemporary times, characterized by its versatile traits and unprecedented challenges in the twenty-first century. Historically, analytical chemistry can be termed as the mother of chemistry, as the nature and the composition of materials are always needed to be iden- tified first for specific utilizations subsequently; therefore, the development of analytical chemistry has always been ahead of general chemistry [2]. During pre-Hellenistic times when chemistry did not exist as a science, various ana- lytical processes, for example, qualitative touchstone method and quantitative fire-assay or cupellation scheme have been in existence as routine quality control measures for the purpose of noble goods authentication and anti-counterfeiting practices. Because of the unavailability of archeological clues for origin tracing, the chemical balance and the weights, as stated in the earliest documents ever found, was supposed to have been used only by the Gods [3]. -
