有人能做这个测试么

扫描电镜(SEM/EDS)

  • Test item: silver metal wine stopper.



    Result: The sample was analyzed using a scanning electron microscope with energy dispersive spectroscopy (SEM/EDS)

    This instrument is capable of detecting berylium and elements with greater atomic numbers(i.e, cannot detect hydrogen,helium and lithium).

    The results of EDS chemical analysis on the sample reveals a three layer plating consisting of chromium over nickel over copper.



    Conclusion: The result for this sample is considered as FDA/GRAS

    这个不就是用SEM+EDS测试镀层成分吗?
