Positive Material Identification

Positive Material Identification (PMI) is the analysis of a metallic alloy to establish composition by reading the percentage quantities of its constituent elements. This non-destructive testing method is to determine the elemental composition of the material using a portable X-Ray fluorescent (XRF) analyzer.

The consequences of using the wrong material can range from costly to disastrous, and may involve loss of property, loss of revenue and even loss of life.

At RTL we use PMI primarily to:

  • Rapidly verify alloys
  • Analyze material that can’t be analyzed through destructive methods
  • Quickly sort materials
  • Initial validation prior to destructive testing

Note: RTL doesn’t perform on-site PMI testing
