ABSTRACT:
Methods for producing a preponderance of gas phase ions having higher order charge states during laser desorption ionization of an analyte are presented, the methods comprising irradiating the analyte in the presence of energy absorbing molecules at a mid-IR wavelength that is offset from an IR absorption maximum of the energy absorbing molecules.
