The difference in the fragment patterns between the high-energy CAD and the other dissociation methods was explained in terms of the internal energy distributions. The dissociation mechanisms of neutral silver bromide cluster Ag 2 Br and silver cluster Ag 3 were also investigated by charge inversion...
the generated ions and electrons are accelerated to position-sensitive MCP/phosphor screen detectors at the top and bottom of the instrument, respectively. Potentials were applied to the ion optics such that velocity mapping conditions were met for both ions and electrons31. On the ion side, the...
In recent years, several studies have been published seeking to extend native mass spectrometry to the determination of binding affinities in the gas3,4,5 and solution phases5,6,7, using the most widespread native mass spectrometry method, nano-electrospray ionisation mass spectrometry (nESI-MS)....
Rationale Soft chemical ionisation techniques including selected ion flow tube mass spectrometry, SIFT-MS, and proton transfer reaction mass spectrometry, PTR-MS, cannot currently quantify individual isomers present simultaneously in samples, a notable example being atmospheric monoterpenes. A possi...

Careful monitoring of the green curve in Figure 1 might lead to the conclusion that the Ni2− signal is lowered when the recombinator is opened and recovers to its initial value when the recombinator is closed, but this difference is marginal, so we cannot be conclusive. The main reason ...
