X-ray Fluorescence Analysis (XRF)
X-ray Fluorescence Analysis is the principal method for all bulk chemical analyses of rocks at the Helmholtz Institute Freiberg for Resource Technology.

How does it work? ►
Secondary X-rays are generated by bombarding a flat sample surface with primary high-energy X-ray. The secondary X-rays show the specific energy pattern of all chemical elements present in the sample. They are either determined by the energy itself or by the respective wavelength. Our PANalytical AxiosmAX spectrometer is a wavelength discriminating device, in which certain wavelengths are separated by diffracting crystals (see picture) and associated to a certain element. The concentration of the element of interest can be recalculated from a calibration.
