Quadrupole Ion Mass Spectrometry
Chiral preference
studies, studies of gas phase clusters, and proteomics are among the
projects tackled with the Finnigan LCQ Deca quadrapole ion trap mass
spectrometer. The LCQ is a workhorse in the Beauchamp group.
The ion trap (denoted on the figure by the endcap and ring electrodes)
is like an "electric field test tube" where ions can be isolated and
subjected to Collision Induced Dissociation (CID). Often, simple
dissociation is not the only result of CID; bond formation, hydration
and dehydration, and many other gas phase processes occur.

trap mass spectrometer.
