Electron Probe Micro Analyzer

JEOL JXA-8530F Electron Probe Micro analyzer

The JXA-8530F is a thermal field emission electron probe micro analyzer combining high SEM resolution with high quality composition analysis of submicron areas. The JEOL JXA-8530F instrument is equipped with 6 WDS detectors (3 for heavy elements and 3 for light elements) and an energy dispersive X-ray spectrometer (EDS). This combination can simultaneously analyse 3 elements WDS + 16 elements EDS plus collect image signals from backscatter and secondary electron detectors.
