OES (Optical Emission Spectrometry) vs XRF for Positive Materials Identification (PMI) and Alloy Analysis

OES analysis in PMI is a recognized technique to verify elemental composition and grade identification of alloys in the metals industry.  A comprehensive PMI program safeguards your facility from alloy mix-ups which can cause costly accidents.  Although there are other instruments that can perform PMI analysis, the most widely used instrument is the handheld XRF.  Find out how the Bruker S1 TITAN can safeguard your PMI program!

Another common method used for PMI analysis is OES (Optical Emission Spectrometry).  Although both XRF analysis and OES analysis provide alloy grade identification as well as elemental composition, there are some distinct advantages to using handheld XRF:

• XRF analysis is a completely non-destructive technique whereas OES analysis leaves a burn mark where the analysis was taken
• XRF requires minimal preparation of the sample, basically a clean surface whereas OES requires a clean, flat, uniform sample
• XRF can analyze small samples such as wires- OES requires a larger sample size
• Handheld XRF is extremely portable with a total weight of less than 5lbs- OES is upwards of 40lbs.
