Positive Material Identification

Positive Material Identification 

Positive material identification or PMI for short, is a method for identifying material alloy grades and composition.

Positive material identification (PMI)

Over recent years there has been an increasing demand for the verification of materials especially in the petroleum refining and petrochemical industries, at Pudsey Test & Inspection Ltd we can offer this to our customers using the latest XRF analysers, working throughout the UK.

X-Ray Fluorescence

The analysers work by taking advantage of X-Ray Fluorescence (XRF). The analysers contain small X-ray tubes that when held up close to an object and fired excite the electrons in the material, this causes the electrons to leave the orbit of the atom. The energy used to eject these electrons are collected by the detector in the analyser. As each element has its own X-ray fluorescence signature, the analyser is able to compare the individual signatures with its database and categorise it.

Testing a range of materials

With improvements in technology coupled with portability and ease of use, the latest XRF analysers allows us to test a whole range of material from large vessels to small welded components and pipe work assemblies without the need of a lab.
