Scott Mercury Verification Gas
For Mercury Analyzer Integrity Testing
Fossil-fueled power plants often monitor their stack's mercury emissions in accordance with EPA 40 CFR Parts 60 & 75. Thermo Fisher Scientific's Model 80i Mercury Analyzer is a popular instrument used for this purpose. It uses small amounts of 900 ppm chlorine gas (in nitrogen balance gas) as part of a recommended weekly integrity test. Drawing on the principle of gas phase titration, elemental mercury vapor is combined with dilute chlorine gas from a small cylinder to form mercuric chloride. The mercuric chloride is then injected into the probe filter and through the entire system to calculate/confirm the conversion efficiency.
Convenient and Cost-Effective
Mercury analyzer integrity testing typically takes place on the stack at the point of injection. Therefore we provide our mercury verification chlorine gas in a SCOTTY™ nonreturnable steel high-pressure cylinder that provides both portability and economical gas quantity. The product comes complete with a matching gas pressure regulator.
