We present data taken from a 0.5 mm ro cylindrical ion trap to track the performance of storage and tandem experiments. The cylindrical ion trap and other mass selecting devices are compared in light of miniaturization. The core components of a cylindrical ion trap mass spectrometer, including ion optics, mass selector assembly, detector, ion source, and housing are described. In these experiments, mass spectral data of xylene is presented. Isolation of the precursor ion was accomplished by modulating the DC ramp voltage, and collision-induced dissociation was accomplished by applying various tickle voltages to the endcaps of the ion trap. Conclusions of projected performance of smaller ion traps (approximately 1 μm) will also be discussed.
