Abstract
Mass spectrometry systems include an ionizer, mass analyzer and the detector, with a high pressure chamber holding the mass analyzer and a separate chamber holding the detector to allow for differential background pressures where P2<P1 which generates gas flow through an unsealed, sealed or partially sealed ion trap and enhances detected signal relative to when P2=P1.
