WDX spectrometers attached to the electron microprobe
General information
All natural and synthetic solid bodies are defined by their chemical composition. The electron microprobe is an instrument that allows accurate and precise determination of chemical composition with micrometer resolution. It is possible to measure and visualize variations in the chemical composition in selected areas of the samples. The electron-optical technology in this instrument allows for correlation of solid-state properties and chemical composition in µm-range. An electron microprobe is an excellent choice for reproducible, highly accurate analytical results that find their use in geosciences, chemistry, physics, materials chemistry in academia, industry, and government institutions.
The electron microprobe can be used for
- quantitative and qualitative analyses of major, minor, and trace elements (> 100ppm / 0.01 wt.%)
- analyses of all elements from oxygen to uranium in solid samples
- visualization of the surface of the sample (back-scattered and secondary electron images, cathodoluminiscence)
- creation of element distribution maps and concentration profiles

Advantages and sample formats
Advantages and sample format
The greatest advantage of the method is the possibility of non-destructive analysis of small sample volumes in µm-range.
Samples
- standard thin and polished sections
- thin sections with dimensions of 28 x 48 mm
- round polished section with diameter of 1'' (25.4 mm)
- round polished sections with diameter not larger than 30 mm
- for non-standard sample formats, contact us and we will find a solution möglich
The surface of the sample must be polished and clean. Before the measurement, the samples will be coated with a thin layer of carbon.
