This is very different from conventional electrospray devices, which define the electric field by the potential difference between the spray device (fluid potential) and the mass spectrometer inlet or atmospheric pressure ionization (API) interface. • As the distance between the electrodes is only a few microns and constttant, an ext remel y st rong and dtblltifildi stable electric field is reproducibly generated, essentially decoupling the ESI process from the inlet of the mass spectrometer.

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.

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.

Scientific supervisor: candidate of chemical science Orlovskaya N. F. Scientific instructor: lecturer Tsigankova Е.V. Siberian Federal University 1 What is the meaning of "petroleomics"? Prof. O. Mallinz (Schlumberger, 2007) introduced the concept of petroleomike as a new scientific direction in the study of petroleum systems, which by analogy with genomics in biology, is based on the concept of the development in each oil distribution system unique continuous series of different size and solubility of resin-asphaltene components in the hydrocarbon matrix. Petroleomics is a new field in petroleum chemistry engineering I am launching through my publication. "To understand function, study structure," said Francis Crick, Nobel Prize winner for revealing the chemical structure of DNA, a discovery that led to genomics. We envision petroleomics being to petroleum science what genomics is to medical science. In short, medicine traditionally treats patients based on symptoms, and the vision of genomics is to predict and treat medical concerns even before symptoms appear. Petroleum science has, similarly, been phenomenological. Establishing structure-function relationships has been precluded in petroleum science because nobody knew the petroleum chemical structure. This is all about to change. Petroleomics promises the ability to predict petroleum properties based on the foundation of elucidating the chemistry of all constituents in a crude oil. In addition, it is necessary to get information concerning Downhole Fluid Analysis in order to exploit petroleum chemistry to understand reservoir architecture.
