ABSTRACT:
Disclosed herein is a three dimensional quadrupole ion trap for analyzing samples. The ion trap includes a pair of opposing end cap electrodes which define a cavity and an axis between them. The ion trap includes a ring electrode attached between the end cap electrodes and circumscribing the axis. Each of the end cap electrodes and ring electrodes are made from Molybdenum to minimize chemical reactivity and to resist thermal deformation.
