Abstract
Methods and systems for generating ions from a liquid sample for mass spectrometry are provided herein. In various aspects, the methods and systems can enhance the break-up of a jet of the liquid sample upon injection into an ionization chamber. In some aspects, methods and systems perturb the liquid sample prior to discharge to increase the internal energy of the sample so as to enhance the formation of liquid droplets when the liquid sample is injected into the ionization chamber.
