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. The sample is fused in a zirconium crucible 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 or a combination with ICP-MS. 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.
