摘要: A mass spectrometry method in which a supplemental AC voltage signal having at least one high power frequency component, and low is applied to an ion trap. Each component has amplitude sufficiently large eject or more selected ions from the trap, by resonantly exciting ions. sufficient induce dissociation (or reaction) of ions, but insufficient resonate for detection. The band frequencies) each match resonance desired mass-to-charge ratio. purpose inducing reaction specific trapped may be parent, daughter, reagent, product undesired products such process In accordance with invention, appropriately components trap during (MS)n CI, combined CI/(MS)n, operation.
