1. Electron Probe Microanalyzer

This laboratory is equipped the Electron Probe Microanalyzer JEOL JXA-8230, with LaB6 and W electron gun, 5 X-ray spectrometers, 10 analytical crystals, and meanwhile equipped with Oxford X-MaxN 20 IE250, and Panchromatic Cathodoluminessence System, PHI-RHO-Z Quantitative Analysis Program and CHIME Dating Program. This device can obtain the probe current range 10-12 ~10-5 A, scanning magnification X 40 to 300000 (WD.11mm), secondary electron image resolution  6nm(W), 5nm(LaB6)(W.D. 11mm, 30kV). This laboratory provides observations and measurements based on back scattered electron images (BSE), secondary electron images (SEI), and cathodoluminescence (CL), and also performs major and trace element compositional analyses on micro-solid materials.
