Summary

Mercury in a sample is oxidized using BrCl. Oxidized mercury in the sample is then reduced to volatile elemental mercury using SnCl2. Elemental mercury is purged with nitrogen and collected on a gold sand trap.

After sufficient mercury has been collected, the trap is heated and desorbed mercury is purged into a cold-vapor atomic fluorescence spectrometer (CVAFS) for quantitation.
