Description
|
This CRM is intended for the calibration of instruments and evaluation of methods for the determination of mercury. This sample of river water was collected from the Ottawa River near Ottawa, Ontario. An appropriate volume of concentrated BrCl, prepared according to reference 4 , was added in addition to a spike of inorganic Hg. The water was aliquoted into 50 ml precleaned glass ampoules and flame sealed. The ampoules were gamma irradiated to a minimum dose of 25 kGy at the Canadian Irradiation Centre, Laval, Quebec. Keywords: Environmental material, Natural water, Surface water, Trace elements, Heavy metals |
Package |
3 x 50 mL The material is packaged in 50 ml glass ampoules stabilized with 0.5% v/v BrCl.
