Positive Material Identification (PMI) is a fast and non-destructive method for verifying the chemical composition of metals and alloys. Portable and cost-effective, PMI can be performed in one of our state-of-the-art labs, or in the field.

Positive material identification is a cost-effective method for confirming general material types. While not as thorough as other chemical analysis methods, PMI is a great option for confirming the alloy or type of large batches of material, testing finished components, re-certifying materials, and evaluating materials that cannot be destroyed, or shipped to a lab.  

At Element, we can detect a large range of metals and alloys, and routinely assist with large or on-site projects to ensure your materials meet the required specification and stand up to the demands of the environment.

Laboratory positive material identification services

Element can perform PMI testing in labs across the US and Europe. Our experts can assist in identifying mixed batches of material, issuing alloy verification certifications and analyzing expensive or unique components without causing damage. 

On-site PMI with portable XRF-analyzer

As part of our On-site Metallographic Analysis, Element offers on-site PMI with a portable XRF-analyzer for identification of medium and high alloyed metals, such as stainless steels, nickel alloys, and copper alloys. 

Our on-site PMI analysis services provide you with a rapid response to your material sorting requirements when shipping materials or parts to a laboratory is too slow or not possible.
