State analysis using EPMA

Estimate bonding states by comparing with standard spectra! Introducing state analysis using EPMA.

In the state analysis using EPMA, changes (shifts and shapes) in the characteristic X-ray peak wavelengths due to differences in the chemical bonding states (ionic valence, crystal structure, coordination number) of oxides and silicates are utilized to estimate the bonding states by comparing with standard spectra. In the identification of two types of copper oxides, when distinguishing between black CuO and red Cu2O by color is difficult, especially for microscopic objects that require an electron microscope, it is possible to grasp the oxidation state using EPMA. Additionally, while XPS is effective for measuring thin oxide layers on aluminum surfaces, EPMA can be used to understand the oxidation state of small foreign particles, bulk materials, and composites. 【Device Specifications】 ■ Manufacturer: JEOL Ltd.
