As the first step of electronic and electrical environmental protection, ROHS has become the most basic access threshold for electronic and electrical products to enter the global market. The quality of electronic and electrical products largely depends on the performance of the materials used and the reliability of the products. The test methods for toxic and harmful substances in electronic information products (hereinafter referred to as "test methods", Standard No. SJ / T 11365-2006) limit the test methods for hazardous elements in ROHS requirements. Among them, X-ray fluorescence spectrometry (XRF), as the most rapid and convenient method, has been developed as a rapid screening method. X-ray fluorescence spectrometry (XRF) can be used to accurately test the corresponding standard samples of lead (PB), mercury (Hg), cadmium (CD), chromium (CR) and bromine (BR). However, the result based on the principle of XRF is only the content of elements, that is to say, if the content of Cr or BR is obtained by this screening test, even if they exceed the standard, it does not mean that the harmful substances (CR VI) and flame retardants (PBB and PBDE) exceed the standard. This test result is only a necessary condition but not a sufficient condition for the corresponding harmful substances.

Jpspec instrument focuses on providing professional services for enterprises that need to detect RoHS. The company's RoHS detector R-350 is RoHS analysis expert, which can carry out nondestructive, rapid and accurate analysis and detection on electronic and electrical appliances, alloy manufacturing, coating / coating, plastics, plastic parts and various harmful elements. Among them, the typical customer of Gree Electric (Nanjing) Co., Ltd., Gree Group has strict internal technical standards, and its products have developed unified control standards to comply with the EU "directive on the restriction of certain hazardous substances in electronic and electrical equipment". Gree Electric adopts our R-350 series RoHS analyzer to meet its requirements for metals, alloys, solders, glass Lead, cadmium, mercury and hexavalent chromium were tested for raw materials such as ceramics. Lead, cadmium, mercury, hexavalent chromium and PBB / PBD were tested for non-metallic materials.
