XRF spectrometer, using standard ceramic sheet sample provided by the authorities for the instrument calibration reference standard, one-time simultaneous analysis of ancient ceramics and glaze samples in Na2O, MgO, Al2O3, CaO, Fe2O3, K2O, MnO, SiO2, TiO2, As, Cr, Cu, Co, Mn, Ni, Pb, Ti, V, Zn, Zr, Ba and other chemical ingredient, and then control the database of ancient Chinese ceramics dating efficacy can be reached off the source. Meanwhile, in order to make better use of X-ray fluorescence analysis equipment nondestructive measurement characteristics, I deliberately oversized vacuum sample chamber according to the industry we need to make to meet the different size, shape detector ceramic samples. In the test ceramic and could also test bronzes (Cu, Sn, Pb, Zn, etc.), precious metals (Au, Pt, Ag, Pb, Cu, Ni, Ru, Rh, Fe, etc.), the chemical composition and the metal coating thickness of soil heavy metal tester, so a multi-purpose heavy metal testing, is necessary to detect antiquarian scientific testing equipment. China National Museum examiners use cases for some mining and Identification of sources and historical relics unearthed was the first to understand its elements, especially when the authenticity of the identification of art, elemental analysis is often important. Because handheld spectrometer can quickly and accurately measure the destructive element content. Such as identification of painting, some pigments (especially modern pigments) contains an inorganic compound, which usually contain inorganic titanium, lead, mercury, copper and zinc and other elements, some of the typical elements of qualitative analysis is often possible to identify different pigments . Identification of ceramics, clay elements usually associated specific origin, which also makes the handheld X-ray spectroscopy has become an important tool for site excavation, it provides information on whether it is of great significance for the protection of cultural relics or art appraisal . (ROHS Directive) 2011/65 / EU of the European RoHS 2011/65 / EU requires the detection of the project is 6, the effective date for the ROHS directive. RoHS Test items are lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6 +) clothing heavy metal tester, polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs). About HBCDD, BBP cloth heavy metal tester, DBP, DEHP and other projects in the instruction is only mentioned in the follow-up priority to assess whether the inclusion of control, is not mandatory for the manufacturer for testing. Shoes heavy metal tester tester _ _ heavy metal heavy metal detector is supplied by Shenzhen Huayi Technology Co., Ltd. Four Seas. Shenzhen Huayi Technology Co., Ltd.
