Abstract

NICKEL METAL, OF 99.99% NOMINAL PURITY AND NATURAL ISOTOPIC COMPOSITION, IN THE FORM OF 0.1MM THICK FOIL AND 0.5MM DIAMETER WIRE HAS BEEN CERTIFIED FOR ITS COBALT MASS FRACTION. THE CERTIFIED VALUE OF COBALT ( < 0.1MICRO/GG.G-1) IS BASED ON 38 RESULTS OBTAINED BY NEUTRON ACTIVATION ANALYSIS, EMISSION SPECTROMETRY WITH INDUCTIVELY COUPLED PLASMA EXCITATION AND ATOMIC ABSORPTION SPECTROMETRY, WHEREAS THE ISOTOPIC COMPOSITION OF THE NICKEL WAS VERIFIED BY THERMAL IONIZATION MASS SPECTROMETRY. THE MATERIAL IS INTENDED TO BE USED AS A REFERENCE MATERIAL IN NEUTRON METROLOGY.
