Principle and Function of Electron Probe


The principle of electron probe
The principle of the electron probe is to inject the electron beam into the surface of the sample with a fine focus. (Or characteristic energy) of the characteristic X-ray can be used to know the type of the element contained in the sample (qualitative analysis). When the intensity of the X-ray is analyzed, the content of the corresponding element in the sample can be known. How much (quantitative analysis).
The role of electron probe
1, phase analysis of metal materials, composition analysis and identification of inclusions in the form of ingredients. The following are the same as the "
2, gold and silver jewelry, precious stones jewelry identification, archaeological and cultural relics identification, and criminal investigation and other areas. The following are the same as the "
3, polymer, ceramic, concrete, biological, mineral, fiber and other inorganic or organic solid material analysis. The following are the same as the "
4, the surface of the solid material coating, coating analysis, such as: metallized film surface coating detection. The following are the same as the "
5, the material surface micro-regional components of the qualitative and quantitative analysis, the surface of the material to do elements of the surface, line, point distribution analysis.
