New Advances in X-Ray Fluorescence Analyzers for Alloy Testing

摘要

For more than 40 years, positive material identification (PMI) of alloys has been performed using standalone, portable, and more recently, handheld x-ray fluorescence (XRF) spectrometers. These portable spectrometers, using a focused beam of x-rays to excite key elements found in the alloy sample, produce a resultant spectrum and thus a digital readout of elemental concentrations. The concentrations of key elements provide industrial inspectors with the ability to verify alloy grades in critical applications avoiding possible catastrophic incidents where an incorrect alloy could have been used by mistake.
