Determination of hafnium at the 10−4% level (relative to zirconium content) using neutron activation analysis, inductively coupled plasma mass spectrometry and inductively coupled plasma atomic emission spectrometry

- We worked out ICP-MS method of Hf determination in Zr and Zr compounds.
- We used NAA method as reference one.
- We obtained pure zirconium matrix by ion exchange (Diphonix® resin).
- These permit to determine ≥1 × 10−4% Hf in Zr sample by ICP MS with good precision and accuracy.
