Claisse has released a white paper including three application notes detailing sample preparation by borate fusion, and dissolution using peroxide and borate fusions, for ICP-OES analyses.
The analysis and determination of metals and trace metals in high silica, alumino-silicate samples and refractory minerals such as catalysts, zeolites and chromites are never easy, mainly because of the dissolution process. Samples containing silica often need hazardous chemicals, microwave digestions, multi-step, and multi-acid digestion which requires the use of HF and HClO4 and can take between one and three hours.
This white paper describes a new approach to sample dissolution using lithium borate and sodium peroxide fusions as quick, safe and efficient alternatives for the dissolution of these specific samples.
