Nitrogen Purged TXRF for the Quantification of Silver and Palladium

25-Jul-2012 | Uwe Karst, Journal of Analytical Atomic Spectrometry, 2012

Total reflection X-ray fluorescence (TXRF) analysis is a powerful technique for simultaneous multi-element analysis. Benefits include limits of detection in the microgram per litre range, limited sample preparation for liquid samples and low operating costs. However, the determination of elements ...
