Positive Material Identification (PMI) is a non-destructive testing (NDT) method that determines the chemical composition of metals and alloys. It’s used to ensure that materials meet specifications and are safe and high quality. PMI is used in many industries, including:

Oil and gas, Power generation, Chemical, Pharmaceutical, Nuclear, Aerospace, and Metal fabrication.

Here are some key points about PMI:

How it works: PMI involves electrically stimulating the surface of a material to create light waves. The light waves are then analyzed to determine the material’s composition.

Methods: Common PMI methods include X-ray fluorescence (XRF) and optical emission spectrometry (OES).

Portability: PMI can be performed on-site on components of various sizes.

Benefits: PMI helps ensure that equipment is made to the correct specifications, which can prevent equipment breakdown.

Tools: A handheld XRF analyser is a common tool used for PMI.
