EDXRF for RoHS
Energy Dispersive spectrometers (ED XRF) measure all elements, down to ppm (mg/kg) levels, and can perform rapid screening of all 5 RoHS elements (Cd, Hg, Pb, Br and Cr).
Benefits for RoHS
- High throughput
- Easy to use with minimal operator training.
- Easy to Learn and Use
- Non destructive testing
Additional Information:
XRF is an elemental technique and is not compound specific; thus, it provides results on total Cr and total Br levels, so additional testing must be done to determine the specific levels of hexavalent Cr (CR+6), and PBB and PBDE if the XRF determines that their levels are inconclusive or above compliance.
X-Ray Fluorescence (XRF) is the phenomenon where a material is exposed to x-rays of high energy, and as the X-ray strikes an atom or molecule in the sample, energy is absorbed by the atom. If the energy is high enough, a core electron is ejected out of its atomic orbital. The void left by the core electron is then filled by an electron from a higher energy shell. This electron shift releases a characteristic energy that corresponds to a specific element. Energy Dispersive spectrometers (EDXRF) measure this energy emitted, and this then corresponds to a specific element. The quantity corresponds to the amount of that element that the sample contains.
