Abstract
A method for producing gas phase molecules includes providing a sample of molecules, the sample being characterized by a charge distribution, and directing acoustic radiation at the sample of molecules to desorb at least some of the molecules from the sample such that the desorbed molecules have a charge distribution that is substantially the same as the charge distribution of the sample of molecules.
