ROHS detector is the X-ray fluorescence spectrometer, which analyzes the principle is the principle of X-ray fluorescence analysis spectrometer. X-ray fluorescence spectrometer can generally be divided into two categories Shui alloy analyzer, wavelength dispersive X-ray fluorescence spectrometer (WDXRF) and energy dispersive X-ray fluorescence spectrometer (EDXRF) Skyray Instrument, wavelength dispersive spectrometer main components include an excitation source, analyzer crystal and the goniometer, detectors, and energy dispersive spectrometer simply excitation source and detector and associated electronics and control components Shui, is relatively simple. Wavelength dispersive X-ray fluorescence spectrometers analyze crystal-resolution analysis of analyte lines, according to Bragg's Law, by measuring the angle Shui heavy metal detector, you can get of wavelengths measured elements: nλ = 2dsinaθ (n = 1, 2, 3 ...) How to split RoHS testing products, classification? A: According to RoHS directive requirements, how to machine products classified scientific and reasonable split, so that testing costs to a minimum is also a major problem, usually divided into metal, plastic and other materials, metal just do detection of heavy metals (lead, mercury, cadmium, hexavalent chromium), plastic material provision needs to be done six (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers), other materials just do the heavy metal testing. 12. How to provide RoHS test sample? A: The manufacturer before submission products, the best advance their own products detailed inspection split, packed and labeled with name and number on each package, respectively, in principle, each component required for detection by weight: 10-20 grams of solid, liquid 10-20 milligrams.
