0.995% Ni + 225ppm Co + 12.72% Fe2O3 (saprolite) OREAS 183 - 10g

CAD$4.00 each

Reference material OREAS 183 is one of a suite of thirteen nickel laterite CRMs (OREAS 182 to OREAS 195) prepared from transitional 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)
