Mercury Sorbent Traps – Speciation

Modified Method 30B for speciation data

Available for Download

Mercury (Hg) speciation sorbent traps are designed to differentiate between elemental and oxidized mercury in the flue gas by capturing the different species in their respective designated sections.

If you need to know your proportion of Oxidized to Elemental Hg, then speciation traps are the solution. These 5 section traps allow you to separate the Hg into the two species.

Currently, there is no method specific to speciation traps, but Method 30B is a great option. When followed, the results are reliable, accurate, and very informative. It is the best way to tell if your Continuous Emissions Mercury Monitors (CEMMs) are working correctly and to evaluate control technologies.
