Hi,
What is the technical difference between chemical analysis and PMI(Positive material identification)? Is it different name only or chemical analysis is a separate test? I found that FRF analyser (X-Ray fluorescence technique) or Optical Emission spectrometer (spark type gun with ultra pure argon gas) are used to find chemical composition of metals during PMI. XRF Analyser will not give carbon content,but spectrometer will give carbon content and other lighter elements also.So, I am with Chemical analysis term!Any help would be highly appreciated.
Thanks
