Other gas-phase ion chemical reactions were explored by using oxygen introduced into the octopole collision cell product ions were injected into and analyzed by the quadrupole ion trap [55]. Reaction of oxygen with Y+, Zr+, and Xe+ was found to proceed rapidly, forming YO+, ZrO+, and Xe neutrals, effectively eliminating interferences by the atomic ions. These ions are particularly difficult... 

When 1 -butene was used as reaction partner and thermalization gas in the first octopole, a new signal with the mass corresponding to the propylidene complex 17 appeared in the spectrum, indicating that an olefin metathesis reaction had occurred. This reactivity was confirmed by mass-selecting either 15 or 16 in the first quadrupole and reaction with 1-butene in the collision cell. The... 

Two papers have been published on the speciation of sulfur using ICP-DRC/CC-MS as a detector. ICP-MS with an octopole cohision cell was used for the detection of a CE separation of metallothionein-like proteins. The collision gas (Xe) and cell conditions were selected to reduce oxygen interference ( 02+) on the main sulfur isotope A completely different approach was taken by Hann et al. who introduced O2 as the reaction gas in the collision ceU, and measured the reaction product As obtaining metal-to-sulfur ratios in...
