Electron Microprobe Lab | GC 027


We currently operate a Cameca SX-100 electron microprobe, equipped with 5 wavelength dispersive spectrometers (WDS) and a Rontec energy dispersive spectrometer (EDS). WDS detection limits are approximately 50-200 ppm. The EDS spectrometer is capable of detecting all elements above sodium (Na).

ImageJ software is used to produce X-ray element maps on the microprobe. Up to nine 512x512 pixel element maps in addition to a backscattered electron image can be obtained simultaneously (or less for larger image sizes). Maximum resolution on any one map is one micron per pixel. The ImageJ software also allows for entire thin sections to be mapped by stitching individual element maps together. Additionally, red-green-blue mosaic maps can also be generated.
