Our copper reagents are hermetically sealed in ampoules to ensure high quality and a long shelf life. Elemental Microanalysis copper reagents have a very high oxygen capacity and are thermally treated to prevent expansion when converted to CuO.

The high purity prevents tailing caused by absorption and desorption of gases caused by impurities in the copper (especially important in the analysis of sulfur). Carbon content (organic contaminants such as oil) is zero.
