EPMA is commonly used to determine the compositions of mineral phases in geological samples but is also used where quantified compositional information is required e.g. metal phases within welds, zoning or compositional variations across minerals or within mineral phases. It is a powerful analytical tool with superior X-ray energy resolution than the commonly used energy dispersive spectroscopy (EDS).

This webinar is aimed at researchers and requires an understanding of what an SEM is and how it works.
