Imaging Mass Spectrometry on the Nanoscale with Cluster Ion Beams Nicholas Winograd* Department of Chemistry, Penn State University, University Park, Pennsylvania 16875, United States ABSTRACT: Imaging with cluster secondary ion mass spectrometry (SIMS) is reaching a mature level of development. Using a variety of molecular ion projectiles to stimulate desorption, 3-dimensional imaging with the selectivity of mass spectrometry can now be achieved with submicrometer spatial resolution and
