Ion Accoustic Wave (IAW) dynamics are usually simulated assuming an isothermal Boltzmann fluid response of the electrons. It has been shown that results from the Boltzmann model may significantly differ from cor- responding ones obtained considering the fully ...
The Low Density Matter end-station at the new seeded Free Electron Laser FERMI@Elettra is a versatile instrument for the study of atoms, molecules and clusters by means of electron and ion spectroscopies. Beams of atoms, molecules and helium droplets as we ...
Results of the mechanistic studies of free-electron based fragmentation methods addressing peptide and protein structure analysis with mass spectrometry (MS), electron capture dissociation (ECD) and electron ionization dissociation (EID), are presented. Se ...
We have applied conformer-selective IR-UV double-resonance photofragment spectroscopy at low temperatures in an ion trap mass spectrometer for the spectroscopic characterization of peptide fragment ions. We investigate b- and a-type ions formed by collisio ...
We present a novel, hybrid ion trap/time-of-flight mass spectrometer that is based on a planar multipole design. Compared with Paul trap/time-of-flight instruments, this design possesses the principal advantages of higher injection efficiency and more homo ...
The function of a peptide is intimately connected to its structure, which in solution is the result of the balance between non-covalent interactions within the molecule and the molecule-solvent interactions. Theory has the power to predict the properties o ...
It is believed that low frequency microinstabilities such as ion temperature gradient (ITG) driven modes and trapped electron modes (TEMs) are largely responsible for the experimentally observed anomalous transport via the ion and electron channels in a to ...
RATIONALE Similar to other mass spectrometric technologies based on ion trapping in a spatially restricted area, the performance of Orbitrap Fourier transform mass spectrometry (FTMS) is affected by the interaction between the trapped ion clouds. One of th ...
We compare product-ion mass spectra produced by electron detachment dissociation (EDD) and electron photodetachment dissociation (EPD) of multi-deprotonated peptides on a Fourier transform and a linear ion trap mass spectrometer, respectively. Both methods ...
We present here the design of a new tandem mass spectrometer that combines an electrospray ion source with a cryogenically cooled ion trap for spectroscopic studies of cold, gas-phase ions. The ability to generate large ions in the gas phase without fragme ...
