different spectrum of radiation that can be analyzed. 5.2.2
PMI tools that use X-Ray fluorescence can not detect:
carbon. 5.2.2
How does Portable Optical Emission Spectrometry determine the elements in a material?
An electric arc causes a spectrum of light to be emitted from the tested material. The light is analyzed. 5.2.3
Chemical spot testing:
Removes a small amount of surface metal that is placed in a filter paper. Small droplets of reagents are used on the sample and different colors indicated different materials. 5.2.5.1
