How to prepare solutions by fusion for AA and ICP analysis?

How to prepare solutions M4 Description: <br />Fusion consists in the mixing of an oxidized sample with a lithium borate flux. This mix is heated to around 1000°C. At this temperature, the flux melts and dissolves samples to form a perfectly homogeneous mass. Finally, the molten material is poured for a rapid dissolution into an acid to be analyzed by Inductively Coupled Plasma (ICP), Atomic Absorption (AA) or any traditional Wet Chemistry method. <br /><br />Typical samples include cements, ores, slag, sediments, soils, rocks, ceramics, pigments and glasses. Sub-oxidized samples such as ferroalloys, alloys, pure metals, catalysts, polymers and sulfides can be processed by fusion after an oxidation step.
