PMI (Positive Material Identification)

Positive Material Identification (PMI) is an essential part of the material testing/material evaluation process that verifies the alloy composition of a given sample conforms to advertised specifications and assuring the chemical composition of the metallic material contains the correct percentages of key elements.

Pine carries a wide variety of portable x-ray fluorescence (XRF) and optical emission spectrometer (OES) instruments for non-destructive testing (NDT) applications to detect materials such as:

  • Carbon alloy steel
  • Stainless steel
  • Aluminum alloys
  • Nickel alloys
  • Titanium alloys
  • Tool steels

We provide our customers with access to the largest PMI fleet in the industry with instruments from manufacturers such as Thermo Scientific, Olympus Innov-Xand Oxford Instruments.
