Abstract: A secondary ultrasonic nebulisation device is disclosed comprising: a liquid sample delivery capillary; a sample receiving surface arranged for receiving a liquid sample from the capillary; and an ultrasonic transducer configured for oscillating the surface so as to nebulise the liquid sample received thereon, wherein the device is configured such that the oscillations of the surface by the ultrasonic transducer cause charged droplets and/or gas phase ions to be generated from the sample.
