context_page_description: Peroxide fusion is used to prepare samples for inductively coupled plasma, atomic absorption analysis and wet chemistry. Sodium peroxide is used to oxidize the sample that becomes soluble in a diluted acid solution. This method allows complete dissolution of numerous refractory compounds like chromite, magnetite, ilmenite, rutile, and even silicon, carbides, alloys, noble metals and materials with high sulfide contents.
  Peroxide fusion can be performed either manually or with automated systems. The latter have the advantage of increasing productivity, improving safety, maintaining repeatable preparation conditions, and avoiding spattering as well as cross-contamination.
