Abstract
A method of analysis is disclosed comprising providing a sample on an insulating substrate such as a petri dish 4 and contacting e.g. the rear surface of the insulating substrate with a first electrode 9. The method further comprises contacting the sample with a second electrode 2 and applying an AC or RF voltage to the first and second electrodes 9,2 in order to generate an aerosol from the sample.
