The photos below show the imaging capabilities as well as the range of data that can be acquired from using our departmental EPMA. For more information about specific functions of the machine, please consult the technician (Dr. Yanan Liu).
1. Examples of SEI Imaging
2. Examples of Energy Dispersive Spectrometer (EDS) Qualitative and Quantitative Analysis
3. Examples of Wavelength Dispersive Spectrometer (WDS) Qualitative Analysis (Wavescan)
4. Example of WDS Quantitative Analysis
5. Mapping Applications: Zoning in Chondrites (courtesy of Royal Ontario Museum (ROM), 2021)
6. Mapping Applications: Nickel (Ni) Concentration
