Current mass spectrometry techniques for the online measurement of organic aerosol (OA) composition are subjected to either thermal/ionization-induced artifacts or limited mass resolving power, hindering accurate molecular characterization. Here, we combin ...
Nowadays, among the instrumentation park of mass spectrometry, Fourier transform mass spectrometers (FTMS), including ion cyclotron resonance (ICR) and Orbitrap FTMS, provide the highest analytical performance for accurate measurements and mass resolution. ...
Mass spectrometry is a powerful analytical technique, which has become invaluable across a wide range of scientific fields, such as "omics" sciences (e.g., proteomics), doping control and forensic sciences, drug development, environmental analysis, geologi ...
A paradigm shift is underway in the field of quantitative liquid chromatography-mass spectrometry (LC-MS) analysis thanks to the arrival of recent high-resolution mass spectrometers (HRMS). The capability of HRMS to perform sensitive and reliable quantific ...
Coupling of motion of the ion clouds with close m/z values is a well-established phenomenon for ion-trapping mass analyzers. In Fourier transform ion cyclotron resonance mass spectrometry it is known as ion coalescence. Recently, ion coalescence was demons ...
We present an approach that integrates ultraviolet (UV) photofragmentation spectroscopy of cold ions with high-resolution Orbitrap mass spectrometry (MS) and uses mathematical analysis of the recorded 2D data arrays for structural identification of biomole ...
A method of analyzing molecules enabling chemical, structural and isomeric or conformational identification of the molecules, particularly in a stream from a chromatographic separation, comprising: generating ions from a sample of molecules to be analyzed; ...
The main objective of this PhD thesis is to link the atomic scale structure to the catalytic properties of self-assembled nanostructures. The growth and characterization of these nanostructures was carried out in an ultra-high vacuum (UHV) chamber initiall ...
An account of stable, uniform and adhesive high-density polyethylene terephthalate Fe-phosphate (FeOx-POx-HDPET) sputtered thin films showing absorption in the visible region up to 700 nm compared to POx presenting absorption below 300 nm. These film were ...
Qualitative and quantitative analyte analysis is omnipresent: from quality control in food, pharmaceutical, biotechnology industries, to new molecular syntheses, detection of explosives and drugs, as well as natural compound mixture analysis, such as crude ...
