ROHS non-metallic detector manufacturer, the eight major heavy metal elements in toys refer to soluble elements, while XRF tester tests the total element content. 2. The eight major heavy metal tests simulate the continuous contact of materials with stomach acid for a period of time after swallowing, in order to determine the concentration of soluble elements. And it does not convert the concentration in the material. Therefore, the test results obtained by using XRF tester for direct testing should theoretically be 50 times larger than those obtained by dissolution testing method.
