Optimizing quadrupole collision cell RF amplitude for tandem mass spectrometryA mass spectrometer includes a collision cell and a system controller. The collision cell includes a plurality of rod pairs configured to generate pseudopotential well through the application of radio frequency potentials to the ...
Fragmentation processes within the cell are modelled showing that the focusing properties within the cell have a striking effect on parent- and daughter-ion transmission.doi:10.1002/rcm.1290040605Stephen C. DavisBarry WrightJohn Wiley & Sons, Ltd.Rapid Communications in Mass Spectrometry...
In addition, the r.f.-only ‘collision cell’ has been important in organic tandem mass spectrometry for 20 years, where it is used to promote collision induced dissociation (CID) and to confine and transport the resultant fragment ions to a downstream mass analyzer [15], [16], [17], [...
ICP–MS with hexapole collision cell for isotope ratio measurements of Ca, Fe, and Se To avoid mass interferences on analyte ions caused by argon ions and argon molecular ions via reactions with collision gases, an rf hexapole filled with he... SF Boulyga,JS Becker - 《Analytical & ...
Collision-induced dissociation (CID), when performed in an RF-only quadrupole is a highly efficient method of fragmenting ions. The low-energy (5–10 eV) CID process may involve direct vibrational excitation by momentum transfer but, in any case, is a very different process from the high-ene...

Particle in Cell/Monte Carlo Collision Method for Simulation of RF Glow Discharges: Effect of Super Particle Weighting A parallel Particle in Cell/Monte Carlo Collision (PIC/MCC) numerical code for glow discharge plasma simulations is developed and verified. This method is ... E Erden,I Rafatov...
Appropriate construction of the target cell allows absolute total destruction cross sections and absolute radiative destruction cross sections to be measured simultaneously. In all cases the two cross sections turn out to be equal in velocity dependence and absolute value within experimental accuracy. ...
This function is similar to the cellular phones’ handover, with two main differences: on a packet-based LAN system, the transition from cell to cell may be performed between packet transmissions, as opposed to telephony where the transition may occur during a phone conversation. This makes the...
