Positive Material Identification, commonly known as PMI can be performed using several test methods. LMATS employs a simple non-destructive test method called as XRF (X-Ray Fluorescence Spectroscopy) by using Thermofisher Niton XLT 818 or Innov-X Alpha and OXFORD Instruments X-MET 7500 analysers. These instruments are widely accepted by various industries and especially the petrochemical industry where the precision test results are paramount.

LMATS is NATA accredited for testing several grades of materials.

XLt-Hand No BG webX-MET 7500Note - The portable XRF method used to determine the chemical composition of the material is valid for the identification of the principal alloying elements only. In most cases this provides sufficient data to enable a reasonably reliable estimate of the material type. This method cannot detect carbon and hence the sole analysis should not be used to select materials for applications where the material’s strength is critical. For detailed steel material identification, either a full chemical analysis should be performed or supplementary mechanical tests should be performed.

LMATS has recently been expanded PMI testing to include :
