Collection and preservation strategies and a routine analysis procedure are developed for elemental analysis of individual atmospheric particles using a scanning transmission electron microscope (STEM) equipped with a super ultra-thin window energy dispersive x-ray detector. These techniques are applied to airborne particles collected at Grand Canyon. The successes and limitations of collection, stabilization and analysis methods and insights into microscopic mixing characteristics of particles affecting visibility at the Grand Canyon will be discussed.
