Hi Simon, Since you are just looking for a sanity check (on what??) here are some Cu-S standards for you. They were published in DOI: 10.1021/es304736y. The Cu-cys sample is not a pure phase, but probably a mixture of cysteine/cystine. But it is likely mostly Cu(I). Further discussion is available in the SI of the paper above. The file is from an old, old version of Athena (0.8x)... hopefully it works for you. Best, Drew Latta ====================================== Drew E. Latta, Ph.D. Asst.

I’m particularly interested in Cu(I/II)-GSH, Cu(I/II)-Cys or similar. I need a sanity check on some fluorescence data I am wrangling. Can anyone help?
