1. A device for identifying substances comprising:
a spectrometer configured for analyzing an analyte, with an entrance for accepting one or more analyte ions and a detector for detecting analyzed analyte ions;
an atmospheric pressure source configured for generating ionizing species;
a mesh positioned between the atmospheric pressure source and the spectrometer; and
a supply adapted to periodically heat the mesh, where the analyte is introduced on or near the mesh, where one or more analyte molecules desorbed from the mesh interact with the ionizing species generated by the atmospheric pressure source to form the one or more analyte ions which enter the spectrometer and are analyzed.
