Mercury Sorbent Traps

Sorbent Traps Category Page Image

Our goal is to provide you with all of your Mercury sampling solutions from the sorbent traps to the reporting. You can rely on us to help you meet your sampling deadlines. With the passing of more stringent EPA mercury emission regulations for coal-fired power plants, cement kilns and other combustion sources, we want to help you meet your compliance monitoring requirements. (Mercury and Air Toxics Standard (MATS), Maximum Achievable Control Technology (MACT).

We start with the best carbon we’ve been able to source and chemically treat the sorbent for optimum mercury adsorption and retention. All sorbent media goes through rigorous QA/QC procedures to ensure that you receive the finest sorbent media available for your monitoring requirements.

We’ve done extensive field and lab carbon screening studies testing in extreme environments of high SO2, particulate, moisture, and high temperature stack conditions to demonstrate our sorbents durable performance and reliable analytical results. Using a newly developed acid gas (SO2/SO3) scrubbing media we are able to minimize breakthrough issues and ensure successful mercury sampling results.

Applications:

PS-12B Trap

Method PS-12B

Sorbent Trap Monitoring System for total vapor-phase Hg from coal-fired power plants and stationary combustion sources. Sampling time can range from 30 minutes to 14 days depending upon the stack conditions.

30B Trap

Method 30B

Reference Method 30B for RATAs of vapor-phase Hg CEMs (continuous emission monitors) and trap monitoring systems, & Hg emission test at coal-fired boilers. Generally for short term sampling.

PS-12B Trap

Speciated

Speciated Mercury Measurement of Flue Gas Requires use of an Air Cooled Probe.

Stack Condition Key:

RATA: Relative Accuracy Test Audits of App K Sampling Systems.

Standard Stack Temp 200-400 degrees F, SO2 Level < 500PPM.

Acid Gases Stack Temp 200-400 degrees F, SO2 Level > 500PPM.

High Temperature Stack Temp > 400 degrees F, SO2 Level < 500PPM.

High Temperature & Acid Gases Stack Temp > 400 degrees F, SO2 Level > 500PPM.
