Abstract
An ion source for a mass spectrometer is disclosed comprising an ionization device which emits a stream of droplets and one or more ultrasonic transmitters which create one or more acoustic standing waves. The acoustic standing waves may be used to further nebulize the stream of droplets and induce internal mixing of the droplets.
