Abstract:

A new visualization method has been put forward to show the three-dimensional stability zones of a quadrupole mass filter placed in the constant uniform magnetic field directed along the quadrupole axis. The three-dimensional zone was represented by a set of two-dimensional sections each of which being an analogue of a stability two-dimensional zone of an intermittent electric quadrupole. The procedure for redetermining the boundaries of stability regions for the two-dimensional sections was applied. The results obtained can be used both in design of new mass spectrometers and in analyses of periodic dynamic system stability.
