Positive Material Identification (PMI)
Fast, accurate and non-destructive Positive Material Identification (PMI) services to verify alloy composition, prevent material mix-ups and ensure compliance with international material specifications.
Accurate Material Verification Without Damage
Positive Material Identification (PMI) is a rapid, non-destructive testing method used to verify the chemical composition of metallic materials and confirm that the correct alloy has been used during manufacturing, fabrication and maintenance.
At Om Metalab, PMI testing helps industries eliminate material mix-ups, improve product quality and ensure compliance with engineering specifications and international standards before components are placed into service.
Our experienced inspectors provide fast, reliable material verification for critical industrial applications where safety, reliability and traceability are essential.
Positive Material Identification Techniques
Om Metalab offers advanced PMI solutions using proven analytical technologies for rapid and dependable alloy verification.
X-Ray Fluorescence (XRF)
Portable XRF analyzers provide fast, on-site alloy identification by measuring elemental composition. Ideal for stainless steel, nickel, copper, titanium and other alloy verification applications.
Optical Emission Spectroscopy (OES)
OES technology accurately determines the chemical composition of metals, including carbon and other light elements that cannot be measured by XRF.
On-Site PMI Inspection
Our portable equipment enables rapid material verification directly at fabrication sites, plants, refineries and customer facilities with minimal operational disruption.
Laboratory Confirmation
Where additional verification is required, laboratory analysis is performed to provide highly accurate quantitative material composition reports.
Why Positive Material Identification Is Important
Incorrect material selection can lead to equipment failure, production losses and serious safety risks. PMI testing verifies that every component matches the required material specification before installation or operation.
Material verification improves quality assurance, supports regulatory compliance and minimizes the risk of costly material mix-ups throughout the supply chain.
