Metal Refining & Recycling
Process streams from metal refining can contain a mixture of elements in various concentrations and chemical forms. This is where XRF fluorescence proves to be very valuable. Most UV-vis methods, used as on-line process control, require multiple steps and reagents for the metal in solution to be in a single oxidation state before analysis.
The C-QUAND online XRF analyzer is a fully stand-alone unit with a fast analysis cycle, it does not require any maintenance nor additional reagents. XRF fluorescence is a direct measurement of the atoms, independently of their chemical forms, therefore no sample preparation is required.
