X-Ray Fluorescence Spectrometer ED-XRF1010

ED-XRF is Non-destructive method of analysis of element from Na (11) to Uranium (92). By using ED-XRD analytical concentration range can be analyzed from 0.1PPM to 100%. This instrument is designed to fulfill the requirements of end-users. More accurate, good precise data, fast measurement of speed(30s-900s). EDXRF spectrometer provides simultaneous measurement of sample containing hazardous elements such as Pb, Cd, Hg, Cr, Br, Sb, As for RoHS. Suitable for every sample, from thin cables and electronic parts to bulk samples

XRF and EDXRF spectrometers are the elemental analysis tool of choice, for many applications, in that they are smaller, simpler in design and cost less to operate than other technologies like inductively coupled plasma optical emission spectroscopy (ICP-OES) and atomic absorption (AA) or atomic fluorescence (AF) spectroscopy. Examples of some common EDXRF applications are: Cement and raw meal: sulfur, iron, calcium, silicon, aluminum, magnesium, etc. Kaolin clay: titanium, iron, aluminum, silicon, etc.; Granular catalysts: palladium, platinum, rhodium, ruthenium, etc. Ores: copper, tin, gold, silver, etc. Cement and mortar fillers: sulfur in ash

This type of XRF instrumentation separates the characteristic x-rays of different elements into a complete fluorescence energy spectrum which is then processed for qualitative or quantitative analysis. Filters positioned between sample and detector are used to improve signal, background reduction, and focus on certain regions of the spectra

Working Principle
The EDXRF spectrometer is designed according to Moseley’s law. The spectrometer consists of a power supply, a light path subsystem, a control circuit, and a personal computer (PC). High-voltage power is supplied to the X-ray tube to emit a primary X-ray, which irradiates the sample. The sample is then stimulated to emit XRF, which is received by an XRF detector. The detector classifies the received photons according to energy and counts the number of photons that correspond to different energy levels. The detector then sends the results to the PC, which completes the qualitative and quantitative analyses.
