Fusion packages Fusion analyses result in complete dissolution of samples and are referred to as ‘total analyses.’ Fusions are typically more aggressive than acid digestion methods and are suitable for many refractory minerals such as chromite, ilmenite, spinel, cassiterite, lithium containing species and minerals of the tantalum-tungsten solid solution series. Sodium peroxide fusion Sodium peroxide is a strongly oxidizing basic flux that renders refractory minerals soluble. Fused in a zirconium crucible digested in diluted nitric acid and the temperature is kept relatively low, allowing the measurement of elements that are volatilized at the higher temperatures of lithium borate fusions. Samples can be measured using ICP-OES, ICP-MS or combination of both. Some laboratories offer an alternate scheme using glassy carbon crucibles (GE_ICP91A50 and GE_IMS91A50) to include Zr, Ag and Hf. Alternative dissolution using hydrochloric acid (GE_ICP92A50 and GE_IMS92A50) is also available. Please contact your SGS customer service agent for the best approach for your samples.
Acid Cold Block Digestion Cold Block acid digestion is a new fast, “near total” acid digestion that uses a combination of HCl (hydrochloric), HNO3 (nitric) and HF (hydrofluoric) acid to digest the samples. A unique combination of strong IR heating and condensation techniques provides very efficient digestion for a wide range of minerals. The multi-element ICP-OES package offered with this scheme is especially suitable for samples where the levels of the base metals (Cu, Ni, Fe, Pb, Zn) are expected to be above the classical 1% range offered with a traditional 4 acid digestion exploration method. Please contact your SGS customer service agent for the best approach for your samples.
