Positive Material Identification (PMI)

Positive Material Identification (PMI) is a specialized testing method which analyses metallic alloys to establish composition by reading the quantities by percentage of its constituent elements.  PMI allows for verification of the exact composition of the materials used, ensuring the alloy used is as specified and that the grade is as expected.  This is important for quality control and safety compliance, to ensure that resistance to heat and corrosion, durability and weldability meet specification.


PMI is a great option for:

  • Confirming alloy of materials prior to manufacture.

  • Testing of finished components.

  • Re-Certifying materials.

  • Evaluating materials that cannot be destroyed, or shipped to a laboratory.

As part of Re-Generate's on-site metallographic analysis, PMI is offered via handheld X-ray Fluorescence (XRF) and Laser Induced Breakdown Spectroscopy (LIBS) Devices.

The Z-200 C+ is a dedicated analyser for alloy analysis including carbon content. It analyses carbon content in stainless, down to 0.007 ppm, for dependable separation of L and H grades. The C+ also analyses carbon steels, including carbon equivalents (CE) for weldability.

The Z uses the technique laser induced breakdown spectroscopy (LIBS), which has many similarities to spark OES.  It fires a pulsed laser at the material to create a plasma and light from the plasma is measured with an on-board spectrometer to determine individual wavelengths and thus what elements are present.

X-ray fluorescence (XRF) is a non-destructive analytical method used to determine elemental concentrations in various materials.  XRF works by striking a sample with an x-ray beam from an x-ray tube, causing characteristic x-rays to fluoresce from each element in the sample.  A detector measures the energy and intensity of each X-ray, which is transformed into an elemental concentration using either a non-standard technique such as fundamental parameters or user-generated calibration curves.

The XRF gun also measures a range of the same elements as the Z, but critically can analyse for Phosphorous (P) and Sulphur (S), two elements that are critical in ascertaining the weldability of various steels.
