Spatially resolved heavy ion induced desorption mass spectrometry

Abstract

Heavy ion induced plasma desorption mass spectrometry was used with a micro-beam in a scanning mode. A 10 μm diameter 84 MeV ⁸⁴Kr⁺⁷ beam was used for the desorption. A target of NaCl and KCl microcrystals was scanned relative to the beam. Mass spectra were obtained as a function of position on the sample.
