Specific activity measurement of ⁶⁴Cu: a comparison of methods.


PMID 24709610

Abstract

Effective specific activity of (64)Cu (amount of radioactivity per µmol metal) is important in order to determine purity of a particular (64)Cu lot and to assist in optimization of the purification process. Metal impurities can affect effective specific activity and therefore it is important to have a simple method that can measure trace amounts of metals. This work shows that ion chromatography (IC) yields similar results to ICP mass spectrometry for copper, nickel and iron contaminants in (64)Cu production solutions.
