Application studies Palladium Analysis Conclusion o The choice of the X-ray target is very important for Pd analysis because of the Pd-L line interferes with Ar-K line o TXRF can accept organic solvent-based diluents o Instrument is easy enough for a technician to be able to run samples at or near the plant floor o Also allows for fast analysis of impurities with small sample size requirements Acknowledgments: Bradley Shaw, David Semin, et.al Analytical and Research Development, Amgen Inc.
