PMI to avoid any potential mix up
Positive Material Identification (PMI), is a well accepted analytical testing technique used within the metal alloy industry whose role is to give a guarantee of a materials chemical composition.
Where this can be performed on-site using simple, portable analysers this allows a number of benefits to be realised. For example a manufacturer confirming every part is to specification, identification of correct alloy grade where a critical part is to be replaced, goods inward inspection to ensure all bought in materials are to specification etc.
Applied correctly simple PMI avoids any potential mix up, costly reworks, out of specification material used incorrectly, and in the worst case failure of a critical component potentially leading to a catastrophic failure of a process and loss of life.
There are two globally accepted analytical methods for simple on-site PMI and these are X-ray Fluorescence (XRF) and Optical Emission Spectrometry (OES).
The X-MET5000 is a rugged hand held portable XRF analyser measuring the key alloying elements in Stainless steel and high alloy grades where PMI is most frequently used. Operation simply involves placing the X-MET5000 against the alloy, pulling the trigger, and after a few seconds the chemical composition and alloy grade is displayed allowing PMI to be performed.
Light Element measurement without vacuum or helium attachments:
The X-MET5100 provides fast, highly accurate laboratory quality chemical analysis of Aluminum and Titanium alloys and can reliably analyze light elements such as silicon and phosphorus from copper, nickel and steel alloys. For the scrap recycling industry the efficient Light Element capability provides added confidence to accurately analyze nickel or copper content and enables more accurate aluminum grade identification.
The PMI-MASTER PRO is a robust mobile OES system, measuring the range of alloys shown above, but in addition to measuring elements such as chrome or manganese in steel, also allows the determination of elements such as Carbon, Boron, Sulphur and Phosphorous at ppm level, which are not possible using portable XRF. Measurement involves holding the pistol against the sample, waiting a few seconds and then the full chemical composition and alloy grade is displayed . A burnspot remains on the surface and proofs the testing of the material.
All analysers offer, simple, rapid, rugged, dependable on-site Positive Material Identification (PMI).
