Each test was done using a freshly calibrated XRF instrument in “Consumer Goods” mode. Testing was repeated on each component to confirm the results. Testing time for each component was for at least 60 seconds. Results are replicable, science-based, and accurate. Metals not listed in the above test results sets were not detected by the XRF when testing in Consumer Goods mode.
