Title: Mass filter having reduced contamination
Inventor: MARTIN RAYMOND GREEN
IPC: H01J49/42
Filed: 2020-05-06
Abstract: An AC-only mass filter 2 is provided upstream of a mass filter 4. The AC-only mass filter has a first AC (e.g. RF) voltage 8 applied to radially confine ions, and a second AC voltage 10 applied to radially excite and attenuate ions which have mass to charge ratios above a mass to charge ratios range transmitted by the mass filter 4. Mass pre-filtering using the AC mass filter 2 may reduce the rate at which contamination of the mass filter 4 builds up. The second AC voltage 10 may comprise two dipolar excitation waveforms applied between different pairs of electrodes of the AC-only mass filter 2 to cause filtered ions to impact on a larger number of electrodes. Also disclosed is a mass filter having a DC resolving voltage applied thereto, wherein the polarity of the DC resolving voltage is reversed one or more times. This may result in reversal of the direction in which any given ion outside the mass transmission window becomes unstable, and therefore spread the ion impacts over a greater surface area of the electrodes.
