In certain instances, metal content may be tested using a Thermo Scientific Nitron Handheld XRF Analyser. This device examines metal to a depth of approximately 8 microns only, and any results obtained through electronic testing must be regarded as indicative rather than definitive, as inaccuracies may occur.
