Abstract:
We present the simulation of a cylindrical ion trap (CIT) at high pressure (5-25 Torr range). SIMION 7.0 software was used for the simulations. The effect of pressure, RF frequency and trap dimensions has been investigated. The shape of stability diagrams at non-zero pressure is drastically different from the one observed in vacuum. Preliminary experimental results are shown, using a r = z = 3 mm-long CIT at 12 Torr for trapping peptide and protein ions.
