EPA Method 30B - Mercury in Sorbent Traps
- Measuring total vapor phase mercury (Hg)
- Using sorbent trap sampling and extractive or thermal analytical technique
- Use under relatively low particulate conditions
- Elemental Hg(Hg0)
- Oxidized Hg(Hg+2) - HgCl2
- Known volumes of flue gas are extracted from a stack or duct through paired, in stack sorbent media traps at an appropriate flow rate
- Sorbant trap collection mitigates potential loss of mercury during transport through a probe/sample line.
- Paired train sampling is required to determine measurement precision and verify acceptability.
- Samples may qualify to be shipped as a hazardous material. Please call for IATA codes if you need them.
- Relative Accuracy Test Audits (RATAs) of vapor phase Hg CEMS and sorbent trap monitoring systems
- New Source Performance Standards (NSPS)
- National Emission Standards for Hazardous Air Pollutants (NESHAP)
- Emissions Trading Programs
- State Implementation Plans (SIPs)
- Operating permits that require measurement of Hg concentrations in stationary source emissions
- No, please contact us if you are interested!
