1. anion detection method editor: British Blue Ion chromatography using oxygen bomb combustion process after the former British blue technology directly into the ion chromatograph for analysis 2. cation and valence: The British blue cation chromatography, ion-selective electrode method atomic absorption method to determine cationic elements can be detected in the valence can be analyzed voltammetry Polarography Rohs pronunciation. / Rous / detection methods can refer to IEC62321: 2008 electrical and electronic products six regulated substances concentration measurement procedure A. First use non-destructive XRF screening, fast and efficient, non-destructive, low cost. But interference factors, a large error. B. digestion, acid digestion after use AAS or ICP-AES determination of Pb, Cd, rohs testing equipment, Hg concentrations. C. Soxhlet concentration polybrominated biphenyls, polybrominated diphenyl ethers, etc. After the extraction was measured by GC-MS. Measuring the concentration of Cr6 + D. colorless surface point test method or use boiling water extraction method, or by using an ultraviolet-visible spectrophotometer EPA3060A test .. Product not RoHS certification, the manufacturer will cause incalculable damage, then nobody cares about your product, we lost the market, if you are lucky enough to enter each other's markets products, once identified, made rohs tester, will face high fines and even Detention, rohs testing equipment, which could lead to the collapse of entire businesses to close. Many large enterprises have long been certified for RoHS research, well prepared, and many products have passed RoHS certification, but there are still many SMEs RoHS certification is still fairly new, scanty, smoke and mirrors, unclear I do not know where to start, I do not know who to turn to certification. 9 How to test editor fact, rohs tester, RoHS certification is not so mysterious, and people are familiar with CE certification, FCC certification, certification similar, provided they have the appropriate qualifications and third-party notary laboratory capacity can provide similar services for enterprises , is that related to your product sent to specialized laboratories for testing, analysis, including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) six hazardous substances Meets RoHS Directive, if they meet can get RoHS compliance reports and certificates, if met, would have to find another alternative to meet the requirements of the product. rohs Tester, phthalic tester, rohs tester is supplied by Shenzhen Huayi Technology Co., Ltd. Four Seas. rohs Tester, phthalic tester, rohs Tester is universal Shenzhen Huayi Technology Co., Ltd. (huayi-universal.com) (www.huayi-univerasl.com) this year introduced a new upgrade, the above picture is only for reference, please call the contact phone book page or image on to obtain the latest information, contact: Guo Fan.
