Numerical Study of Directionality of Ion Ejection In Axially Symmetric Ion Traps
(2013-02-13)
In the normal operation of quadrupole ion trap mass spectrometers, the trapped ions are ejected symmetrically through both the upper (detector) and lower(source) endcap electrodes during mass selective boundary ejection ...
Axially Symmetric Equivalents Of Three-Dimensional Rf Ion Traps
(2013-09-13)
This thesis presents axially symmetric equivalents of three-dimensional rf ion traps. Miniaturization in mass spectrometry has focused on miniaturizing mass analyzers. Decrease in mass analyzer size facilitates reduction ...
A Preliminary Investigation Of The Role Of Magnetic Fields In Axially Symmetric rf Ion Traps
(2013-07-16)
Axially symmetric rf ion traps consists of a mass analyser having three electrodes, one of which is a central ring electrode and the other two are endcap electrodes. In the ideal Paul trap mass spectrometer, the electrodes ...
