Mercury Sorbent Traps
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).
All sorbent media goes through rigorous QA/QC procedures to ensure that you receive the finest sorbent media available for your monitoring requirements.
Sorbent Trap Monitoring System for total vapor-phase mercury from coal-fired power plants and stationary combustion sources. Sampling time can range from 30 minutes to 14 days depending upon the stack conditions.
Reference Method 30B for RATAs of vapor-phase mercury CEMs (continuous emission monitors) and trap monitoring systems, and mercury emission test at coal-fired boilers. Generally for short-term sampling.
Speciated mercury measurement of flue gas requires the use of an air-cooled probe.
Stack condition key:
RATA: relative accuracy test audits of Appendix K sampling systems
Standard: stack temperature 200-400ºF, SO2 level < 500 PPM
Acid gases: stack temp 200-400ºF, SO2 level > 500 PPM
High temperature: stack temp > 400ºF, SO2 level < 500 PPM
High temperature and acid gases: stack temp > 400ºF, SO2 level > 500 PPM
Sorbent trap features:
- High-capacity impregnated carbon
- Low mercury background levels
- Custom spiking available
- Variable testing duration
- Textured, easy-grip caps
- Accurate leak checking
- Durable glass tubes
- Protective transport tubes
- Chain of custody included
- Long-term storage
Any trap can be customized for special stack conditions. For high particulate and wet stacks, we recommend using the Apex Sorbent Trap Shield to reduce sorbent trap plugging.
