AVO personnel use this FEI Quanta 200 electron microscope for rapid analysis of volcanic ash. The microscope is equipped with secondary electron (SE) and backscatter electron (BSE) sensors, as well as a highly sensitive silicon drift detector energy-dispersive X-ray spectroscopy (SDD EDS). This instrument is well suited for acquiring high-resolution images of micron-size ash particles and for identifying mineral phases. The electron microscope is part of the Advanced Instrumentation Laboratory of the University of Alaska Fairbanks https://www.uaf.edu/ail/.
