I prepared in mix standards but not responding Hg only?
I mixed standards for a spectrophotometry test, and the purpose of the experiment was to measure the concentration of different materials.
Ah, I understand now. It could be possible that the Hg material was not mixed properly or that there was a problem with the instrument used to measure it. Have you tried redoing the experiment with new materials and checking the calibration of the instrument?
