Positive Material Identification (PMI)
Quick, non-destructive composition analysis. XRF for most alloys, OES for carbon-bearing steels, LIBS for the lightest elements.
Positive Material Identification (PMI) is a quick, non-destructive analysis technique to determine the composition of materials — especially alloys and crystalline structures. There are three main PMI techniques used to measure product and determine the constituents of materials.
Techniques
Methods used in PMI
OES
Optical Emission Spectrometry
- Carbon content measurement (low-level C)
- Steel grade verification
- Detecting elements XRF can't see (Be, Li, B)
LIBS
Laser-Induced Breakdown Spectroscopy
- Lightest-element detection (H, Li, Be, B, C)
- Carbon equivalency for weld procedures
- Field alloy verification with no radiation source
