Total trace metal impurities in 89Zr products, as measured by MP-AES. Values represent mean ± standard deviation, corrected for the fraction of the total production activity tested. TBP resin-based isolations of 89Zr-chloride (n = 3) and hydroxamate resin-based isolations of 89Zr-oxalate (n = 3) were performed from full natY target masses. Samples converted from 89Zr-chloride to 89Zr-oxalate (n = 3) were obtained from an aliquot of a full production run. *Testing for Mo, Cr, and Cu was not available for 89Zr-oxalate products.
