Positive Material Identification PMI using the XRF technique is a pmi test method which gives fast and reliable results for all your material identification needs.
XRF works by using a beam of X-Rays emitted into a sample piece, the atoms within the sample absorb the energy from the X-Rays, become agitated and begin to emit ultraviolet light. Each element produces a unique range of ultraviolet light and there for its own fingerprint of energy. This fingerprint is then measured by the analyser, therefore enabling the equipment to accurately measure the percentage amounts of elements within a sample. This is then compared with the equipment’s vast data base of materials and a result is given on the composition of the material being tested.
The portable hand held XRF analysers can be used to identify a variety of stainless steels, Chrome-Moly (Cr-Mo) steels, Tungsten and Vanadium steels, low alloy and tool steels, Nickel, Copper, Titanium and Aluminium alloys as well as a range of exotic alloys such as Tantalum and Zirconium. We can offer a full detailed analysis of up to 30 elements for each individual sample or create a bespoke analysis for specific customer needs.
Positive Material Identification Inspection can be carried out either in a workshop, on in service items at sites around the country or at our purpose built laboratory in the Midlands.
