EPMA analysis requires the samples to be mounted (on glass slides or as a resin mount) and polished flat. If the samples are not inherently electrically conductive they require a conductive coat first be applied (typically carbon), AAC staff will undertake this.
A variety of holders are available to accommodate the most typical sample formats.
48mmx28mm (European / Universal format)
46x27mm (American format)
32mm diameter (maximum)
