High Purity Salts for Trace Analysis

Melting digestion is used for solid samples like ores, rock, metals, alloys, ceramic, and cement, in order to obtain a homogenous residue, which can be dissolved in diluted acids. Our salts for trace analysis are very high purity, with metal traces typically below 10 μg/kg (10 ppb).
