Instruction

DW-NP-5010A energy dispersive XRFhas very wide application. It can do qualitative, quantitative and no sample analysis. Such as block sample, powder or liquid samples, from the 4th element in the periodic table beryllium (Be) to the 92rd element uranium (U), almost all of the elements can be accurately analyzed. The analytical concentration range can be from 0.1 PPM to 100%, and even up to 100% of the elementconcentration can be directly measured without dilution.XRF analysis method has the advantages of simple sample preparation, wide determination range of elements, high determination accuracy, good reproducibility, fast measurement speed (30s-900s), no environmental pollution and no destruction of samples.

Working principle The original X-ray produced by X-ray tube and high voltage is irradiated on the sample after being properly filtered by the optical filter. The characteristic X-ray (called X-ray fluorescence) of the elements contained in the sample is stimulated. X-ray fluorescence spectra were obtained by using X-ray detectors with high energy resolution. Different elements formed different spectral peaks on the spectra.The strength of the spectral peak is directly proportional to the content of elements in the sample. The energy spectrum detected by the detector is analyzed by the computer. The types of elements contained in the sample are qualitatively analyzed by the position and shape of the spectral peak.

Application DW-NP-5010A energy dispersive X-ray fluorescence spectrometer (XRF) is widely used in environmental protection, geology, mineral, metallurgy, cement, electronics, petrochemical, polymer, food, medicine and high-tech materials and other fields, playing an important role in product research and development, production process monitoring and quality management.In addition, the instrument can be used in archaeology, building materials, RoHS directive and other industries. It is the enterprise quality control ideal choice.
