Method Overview

• Measuring total vapor phase mercury (Hg)
• Using sorbent trap sampling and extractive or thermal analytical technique
• Use under relatively low particulate conditions

Target Compounds

• Elemental Hg(Hg⁰)
• Oxidized Hg(Hg⁺²) - HgCl₂

Performance Tips

• 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.

Shipping

• Samples may qualify to be shipped as a hazardous material. Please call for IATA codes if you need them.

Applications

• 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

Accreditation
