Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
Electron Beam Induced Deposition (EBID) allows deposition of three-dimensional micro- and nano-structures of conductive and insulating materials on a wide range of substrates. The process is based on the decomposition of molecules of a pre-selected precurs ...
Ionization energies (IE) of [M + zH]z+ (z+) electrospray-produced polypeptides were detd. by electron ionization in a Penning cell of 4.7 and 9.4 .T Fourier transform mass spectrometers. For z = 1+ and substance P, the found IE value of 11.0+-0.4 eV is in ...
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 ...
Recent advances in peptide fragmentation techniques and mass spectrometry have opened up the possibility of combining peptide sepn. techniques, such as capillary electrophoresis (CE) and capillary liq. chromatog., with Fourier transform ion cyclotron reson ...
New low-energy electron injection systems based on indirectly heated dispenser cathodes facilitate electron capture dissocn. (ECD) in Fourier transform ion cyclotron resonance (FTICR) mass spectrometry. In this joint report, details are presented of the de ...
The time-resolved fluxes of negative polysilicon hydride ions from a power-modulated rf silane plasma have been measured by quadrupole mass spectrometry and modeled using a simple polymerization scheme. Experiments were performed with plasma parameters sui ...
Trace contaminants in sputter atmospheres (10(-2) mbar Ar) are determined with a mass spectrometer whose ionizer is directly exposed to the process pressure, whereas the quadrupole filter is kept at high vacuum. The background limitations inherent to conve ...
A new mass spectrometer of the omegatron type has been designed and tested. This new device, which we have called the resotron, combines the extremely low permanent outgassing and pumping rates of the omegatron (less than 10-11 torr liter/sec. and 10-3 lit ...
The efficiency of conventional aerodynamic isotope sepn. can be improved by 2 orders of magnitude with the aid of a relatively weak cw IR laser which is used to induce isotopically selective condensation. Overall isotope enrichment factors in excess of 2 a ...
Predissocn. spectra were detd. for SF6-Ar clusters in a mol. beam by monitoring the decrease in a specific mass spectrometer signals induced by a tunable continuous-wave CO2 laser. A red shift occurs downstream from the nozzle as the gas expands and the cl ...
