Library of Phase Spectra

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 18, 2025 | Last Modified: 20200929
We developed and tested a new method for in situ characterization and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. This library of phase spectra is provided to show the typical energy dispersive spectrum of the inorganic particulate matter identified in lung biopsy sections.
