AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We present in this work a new technique, which combines laser photofragmentation spectroscopy with tandem mass spectrometry, for structural investigations of biomolecular ions in the gas phase. A novel apparatus was designed and built for the implementatio ...
In this thesis report, we describe a novel home-built instrument designed to study the spectroscopy of biomolecular ions in the gas phase and at low temperature, and we present the first experimental results obtained on protonated aromatic amino acids. The ...
Ion traps are an increasingly common presence as mass analysers in commercial bench-top mass spectrometers. Such instruments, usually interfaced with electrospray ionisation or nanospray sources, are invariably aimed at organic and biological applications, ...
Ion-pair reversed-phase high-performance liq. chromatog. (IP-RP-HPLC) has been evaluated as a method for the fractionation and desalting of ribonucleic acids prior to their characterization by electrospray ionization mass spectrometry. Monolithic, poly(sty ...
The present work shows that the electrochemical properties of electrospray ionization (ESI) can be used to add functions to the process. As example, we show how the choice of the electrode material can be used to study interactions between metal ions and b ...
The vacuum deposition of complex functional molecules and nanoparticles by thermal sublimation is often hindered due to their extremely low vapor pressure. This especially impedes the application of ultrahigh vacuum (UHV) based analytical and surface modif ...
The present invention relates to a method and a device for irradiating ions in a ion cyclotron resonance (ICR) trap with photons and/or electrons. For electron irradn. a hollow electron emitter is used, through the hole of which a light beam can be sent in ...
In the present work, a polymer microfabricated microsprayer is characterised and tested for the mass spectrometric analysis of biomolecules, in particular in the context of protein mass spectrometry and proteomics. As the core of this work deals with analy ...
The aim of this work has been to design, and fabricate a miniaturized electrospray-type interface for mass spectrometry analysis, which allows the nebulization of solutions by applying a high potential difference between the source and the mass spectromete ...
Multitrack electrospray chips (MTEC) were fabricated by UV-photoablation of polyethylene terephthalate (PET) substrates. They are composed of an array of up to six microchannels that are successively used as electrospray ionization (ESI) emitters for mass ...
