Upper stability island of the quadrupole mass filter with amplitude modulation of the applied voltages

Increase in quadrupole mass filter resolution at separation in narrow band stability island (X-band) formed by biharmonic resonance excitation of ion oscillation is discussed. X-band and the normal working quadrupole mass filter modes are compared at theoretical resolution of 10,000 and different separation times. Transmission curves, acceptance ellipses parameters, and acceptance characteristics are obtained by numerical simulation. Transmission coefficients are approximately the same in both modes. Dependence of acceptance ellipses parameters on ion inlet phases has a complicated oscillating form in the X-band mode. Acceptance contours calculated for given transition levels have been compared. At low acceptance level, the combined acceptance in the X-band mode was found to be one order of magnitude higher than in the normal mode.

Overall Performance

As the main body of the inductively coupled plasma mass spectrometer (ICP-MS), quadrupole mass filter’s performance will largely affect the overall performance of the instrument. Its main performance parameters include the range of mass analysis resolution and the abundance sensitivity. In this article, we have analyzed simulated and then studied its several main performance parameters which affects the instrument.
