OREAS 349
Артикул: 349
OREAS 349 is a replacement for OREAS 350. It is a zinc concentrate certified
reference material (CRM) sourced from the McArthur River Mining operation
located in the Gulf of Carpentaria region in the Northern Territory of
Australia. The mine is situated about 900 km southeast of Darwin. The major
sulphides are pyrite, sphalerite and galena, with lesser chalcopyrite,
arsenopyrite and marcasite. Twenty-eight laboratories participated in the
certification program to determine:
Zn by classical volumetric titration
Multi-elements by 4-acid digestion with ICP-OES and MS
S by infrared combustion furnace
Specifications
- State: primary
