OREAS 183

SKU: 183

Reference material OREAS 183 is one of a suite of thirteen nickel laterite
CRMs (OREAS 182 to OREAS 195) prepared from saprolitic ore source materials.
These were supplied by Anglo American Brazil Limitada from the Codemin Nickel
Mine located in the state of Goiás and ~300 kms from the port of Santos, Brazil.
It has been certified for Ni, Co, Al2O3, C, CaO, Cl, Cu, Cr2O3, Fe2O3, K2O, MgO,
MnO, Na2O, P2O5, SiO2, S, SO3, TiO2 , Zn and LOI. Nineteen commercial analytical
laboratories participated in the certification program with characterization of
this suite of 20 analytes by the following methods:

Ni, Co, Al2O3, CaO, Cl, Cu, Cr2O3, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SiO2,
SO3, TiO2 and Zn by lithium borate fusion with X-ray fluorescence (17
laboratories)
Ni, Co, Al2O3, CaO, Cu, Cr2O3, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SiO2,
SO3, TiO2 and Zn by lithium borate or sodium peroxide fusion with ICP-OES (12
laboratories)
carbon and sulphur by infra-red combustion furnace (11 laboratories)
loss on ignition (LOI) at 1000°C (18 laboratories)
