A: Hexavalent chromium, cadmium, mercury, lead, polybrominated biphenyls and polybrominated diphenyl ethers.

A: 1,000ppm (hexavalent chromium), 100ppm (cadmium), 1,000ppm (mercury), 1,000ppm (lead), 1,000 ppm (polybrominated biphenyls) and 1,000ppm (polybrominated diphenyl ethers).

A: ROHS detection, full elemental analysis of all types of materials and plating thickness of metals.

A: Principle: Stream of electrons generated through high voltage flows into the X-ray tube and target material shall generate primary X-rays, which shoot into the sample products being tested after filter and aggregation and generate secondary X-rays, that is X fluorescence we usually refer. After being detected by the detector, X fluorescence is amplified and undergoes data reduction, which is entered the computer. Finally, the computer calculates the results we need.
