*Since the other group saw small peaks at the lower end of their range, with the highest at 60 [Au/ADA], and we saw purple solution at 25 [Au/ADA], we decided to make a new set with mole ratios 6.7-40. | *Since the other group saw small peaks at the lower end of their range, with the highest at 60 [Au/ADA], and we saw purple solution at 25 [Au/ADA], we decided to make a new set with mole ratios 6.7-40. |
