X-Ray Fluorescence
X-ray fluorescence is a method to identify materials and measure film thicknesses.
Once the composition of a layered system is known, film thicknesses can be determined.
First the instrument is calibrated to the particular layer system, e.g. Zn on Fe. Then the thickness of the Zn layer on the Fe substrate can be determined to an accuracy of 1 µm within 30 sec.
X-ray fluorescence can also be used to determine the chemical composition of alloys. Different types of steel can be distinguished easily.
Services
- Determination of chemical composition: which elements are present at what percentage
- Qualitative and quantitative analysis from potassium (AN 19) to lead (AN 82)
- Thickness measurements on layer systems of known composition
Fields of application
- Material analysis of various steels (e.g. V2A 1.4301 and V4A 1.4401 are easily distinguished)
- Non-destructive analysis of solders on PCB’s
- Thickness measurements, e.g. Zn on steel
- Not applicable for Al-alloys!
