Abstract: Systems and methods are disclosed herein that prevent over-production of acoustically ejected droplets into a mass spectrometer, without increase to the time required to conduct pre-ejection sample analysis. This is accomplished by decoupling the repetition rate of energy pulses delivered to the sample during an analysis mode from the repetition rate of energy pulses delivered to the sample during ejection mode. The repetition rate during analysis is higher than the repetition rate used during droplet ejection, which is reduced to a level that can be ingested by the acoustically emitted mass spectrometry system.
