The automated XC-6000EPC MercSampler™ for Sorbent Trap Monitoring Systems is designed for continuous dual sampling of vapor-phase mercury emissions from stationary combustion sources, in accordance with the U.S. EPA Clean Air Mercury Rule (CAMR) published in CFR 40, Part 75, Appendix K, Part 63 PS-12B and to conform to new expected regulations. Performance Specification 12B: Specifications and Test Procedures for monitoring total vapor phase mercury emissions from stationary sources using a Sorbent
Trap Monitoring System.

The purpose of performance specification 12B (PS 12B) is to evaluate the acceptability of sorbent trap monitoring systems used to monitor total vapor-phase mercury (Hg) emissions in stationary source flue gas streams. These monitoring systems involve continuous repetitive in-stack sampling using paired sorbent media traps with periodic analysis of the time-integrated samples. Persons using PS 12B should have a thorough working knowledge of methods 1, 2, 3, 4, 5 and 30B in appendices A-1 through A-3 and A-8 to this Part 63.

Power generation utilities will be able to measure and obtain accurate and reliable mercury emissions data in order to determine emission levels and develop control strategies. Power generation utilities may choose from either Continuous Mercury Monitors or Sorbent Trap Monitors like the Apex XC-6000EPC for Mercury Emissions Monitoring.
