Direct bonding has been observed to occur between SiF3 + and the rare gases xenon, krypton, and argon in the gas phase at low collision energies and, in the case of xenon and krypton, also at high collision energies. The kinetics of low-energy additi

The dynamic reaction cell (DRC) is a rf/dc quadrupole which may be pressurized with a reactive gas in order to promote ion–molecule reactions intended to suppress plasma-based isobaric interferences for trace elemental analysis. The bandpass of the
