Hi cell, I once tried to analyze for Br with our ICP-MS 7800, and I got really good calibration line for mass 79 and 81. However, my sample was a water leach sample without any other possible contaminants. Detection then was something like 1 ppb in the water. After this first experiment my client only wanted to focus on the Si content in the same samples so I skipped doing the Br content after that.
Br is volatile so I don't know if you can do it if you have to digest samples first!
Yes you can do Bromine fairly easily, however, it works best in an alkaline matrix since the carryover is terrible in acid. I recommend a 1% NH4OH matrix. I normally make a Br only method and run it standalone.
