Description
|
This certified reference material is intended for the calibration of instruments and evaluation of analysis methods for the determination of isotope ratios of mercury. The reference material was prepared by dilution of NIST SRM 3133 (Mercury Standard Solution) with high-purity water to yield a mass fraction of inorganic mercury of approximately 5 mg kg-1. An appropriate volume of concentrated BrCl, prepared according to reference was added as a stabilizer to result in a volume fraction of 0.5%. The material was bottled and flame sealed in cleaned amber glass ampoules in approximately 2 mL aliquots. The ampoules were gamma irradiated to a minimum dose of 25 kGy at the Canadian Irradiation Centre, Laval, Quebec to inhibit microbial activity. keywords: Isotope ratio measurement |
