Thermo Fisher Scientific Shier Scientific Spectrometer, ARL Spectrometer and Nitong Spectrometer, I believe some friends of these spectrometer brands must be very familiar with them. ARL Company and Nitong Company are both sub-brand companies acquired by Thermo Fisher Scientific Shier Technology. Hand-held X-ray fluorescence (XRF) technology is another technology commonly used by recyclers such as pawn shops and jewelry stores. Using NITON XRF precious metal analyzer, workers can detect the elemental composition of all gold and precious metal jewelry, and determine the existence and concentration of other trace elements, alloy elements and dangerous heavy metal elements, which may affect human health and the valuation of articles.
