The SEMs here within Memorial University's Bruneau Centre include a FEI Quanta 400 for serving general applications in mineralogy, biology, engineering, archaeology, physics and chemistry, and a FEI MLA 650F for serving applications that demand higher resolution. Both SEMs are also capable of environmental SEM (ESEM), which refers to these SEMs' capability for working at variable pressures or near atmospheric pressures instead of limited to high vacuum. ESEM also allows for almost any specimen to be examined, including wet and non-conducting specimens.

For accommodating the variety of information available from electron interaction, our SEMs are also equipped with high throughput energy dispersive x-ray (EDX) analytical systems from Bruker, an electron backscatter diffraction (EBSD) system from HKL, and cathode-luminescence (CL). Both SEMs are also capable of x-ray aided image analysis, i.e., Mineral Liberation Analysis® or MLA®. The MLA software automates image acquisition, stage movement and x-ray acquisition for spatially quantifying mineral abundances and associations of areas as large as a typical thin section of rock.
