			The Electron Microprobe Facility at NASA Glenn is equipped with a scanning electron microprobe which can analyze elements from Be through U with sensitivities ranging from 100% to 50PPM. The microprobe is typically used for detailed microchemical analysis.   Above: Quantitative elemental maps   JEOL 8200 Super Probe Five two-crystal WDX spectrometers Analysis Be-U with 100% to 50PPM sensitivity 1-2% relative analytical accuracy 1.0 micron spatial resolution Typical analysis time 10s for major components and 300s for trace components Simulataneous EDX-WDX quantitative analysis   Above: Technician operating the JEOL 8200 Electron Probe.   For further information please contact Laura Evans Microprobe Example + View example
