Application Note: EDXRF Analysis of Precious Metals in Recycled Automotive Catalytic Converters
3 January 2012

The new method presented in this note demonstrates the determination of precious metals in catalytic material. A calibration method was built using the Rigaku RPF-SQX Fundamental Parameters template, an advanced FP program that automatically deciphers overlapping elemental peaks and models the sample matrix using fundamental XRF equations. This allows for a measurement of elemental concentrations without the need for known assayed calibration standards.
