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 analysers.

These instruments are widely accepted by various industries and especially the petrochemical industry where the precision test results are paramount.

LMATS also deploy Spark Atomic Emission Spectroscopy technologies
