Due to the need to keep magazines and trace elements to a minimum ppm range in cast copper tubes using scrap metal as the base material, a spectral analyser is now an essential instrument for producing copper tubes from scrap metal. Spectrum analysers can be used to analyse all major alloying elements and identify low levels of impurities, trace elements and elements of concern in the metal, up to 20 elements, and can help copper casters better monitor the purity of their output.
