The development of a computer program designed to simulate the performance of the mass filter in an ideal quadrupole mass spectrometer (QMS) is described. The simulation program provides flexible input parameters to allow the user to investigate the ion trajectories and transmission efficiency for d
The ion motion inside quadrupole mass filters is described for a and q values close to those corresponding to the stability region tip. The conventional solutions involving the constant-amplitude series of sine functions, which vanish for the stability region tip, were replaced by Mathieu functions
A novel hybrid tandem mass analyzer, coupling a quadrupole ion trap with a quadrupole mass filter, has been constructed to permit mass analysis of ions ejected from the ion trap. The initial application of this instrument is the investigation of the origin of mass shifts in the ion trap due to ion f
