Spectra collected from pure silver, sterling silver (92.5w% Ag and 7.5 w% Cu) and pure copper plates before and after artificial sulphidation, and before and after a reductive plasma treatment with a remote helium plasma at atmospheric pressure. Reference spectra were collected from Ag2S, Cu2S and CuS powders pressed into pellets. The spectra were collected at the NanoESCA beamline of the Elettra storage ring.
