Abstract

Neutron activation analysis was used to analyze Zn concentrations in high-purity GaAs. A combination of chemical separation of the neutron-induced 65Zn from the GaAs-matrix with anion-exchange chromatography and ultra-low level gamma-ray spectrometry in an underground laboratory was applied. Zn concentration ranged from 2.1 to 51 ng g-1, and detection limits from 0.018 to 0.059 ng g-1 were obtained.
