Preparation and Certification of IRMM-081a and IRMM-086, 239Pu Spike Isotope Reference Materials
Highly enriched 239Pu Spike Isotopic Reference Materials (IRMM-086 and IRMM-081a) have been prepared at IRMM.
The certified values for IRMM-086 of 3.752 4(22)*10-6 mol 239Pu per g of solution and for IRMM-081a of 3.745 8(26)*10-7 mol 239Pu per g of solution have been established by mass metrology and subsequently verified by isotope dilution mass spectrometry. The plutonium isotopic composition has been determined by thermal ionisation mass spectrometry and calibration of these measurements by means of synthetic mixtures.
The Isotopic Reference Material is supplied in a sealed glass ampoule containing 5 mL of a 5 M nitric acid solution.
These Isotopic Reference Materials are part of a systematic IRMM programme to supply Spike Isotopic Reference Materials of various isotopes at different concentrations.
