Element’s Positive Material Identification (PMI) testing is a fast, reliable, and non-destructive solution for verifying the chemical composition of metals and alloys. With services available both in our state-of-the-art labs and on-site, we ensure your materials meet strict industry standards, enhancing performance and ensuring compliance without delays or damage.

What is Positive Material Identification (PMI) Testing?

Positive Material Identification (PMI) is a non-destructive and portable testing method used to confirm the types and percentages of elements in a material. Often performed with an “XRF gun” (X-ray Fluorescence device), PMI is a cost-effective option for verifying alloy composition, identifying general material types, and evaluating materials in large batches. 

This service can be conducted on finished components, or items that cannot be destroyed or shipped to a lab. While PMI does not detect carbon, it is particularly useful at various stages of the manufacturing process and for re-certifying materials after production.

Benefits of PMI Testing with Element

• Global Reach & Local Support: Element can perform PMI testing in labs across the US and Europe. Our experts can assist in identifying mixed batches of material, issue alloy verification certifications, and analyze expensive or unique components without causing damage. 
  
• Certified Alloy Verification: At Element, we can detect a wide range of metals and alloys, and routinely assist with large or on-site projects to ensure your materials meet the required specifications and stand up to the demands of the environment.
  
• Fast, Non-Destructive Testing: Element’s PMI testing delivers rapid and accurate results without damaging your materials, saving you time and reducing costs associated with delays.
  
• Expertise You Can Trust: Our PMI services are conducted by employees with decades of experience in materials testing, ensuring that your materials are evaluated by industry-leading specialists who understand your specific needs.

On-site PMI testing with portable XRF-analyzer

Shipping large, heavy, or sensitive materials to a laboratory can be time-consuming and costly. As part of On-site Metallographic Analysis, Element offers portable PMI testing using advanced XRF analyzers for medium and high-alloy metals such as stainless steels, nickel, aluminum, titanium, and copper alloys.

 This service provides rapid results when fast project timelines or logistical constraints make lab testing impractical. Our team of PMI experts travels directly to your site, offering precise and non-destructive material verification that ensures your project stays on track without costly delays or interruptions to your operations.
