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.  

Our 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. We can detect a large range of metals and alloys, and routinely assist with large or on-site projects.
