MercSampler - Model XC-6000EPC-W - Automated Sorbent Trap Monitoring System
From Mercury and Gas Sampling Equipment
The automated XC-6000 EPC 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 MATS published in 40 CFR, Part 60-63, Appendix A, Subpart UUUUU and is MATS compliant. 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 1...
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
The XC-6000EPC mercsampler simplifies most sampling requirements by automating data acquisition, sample flow adjustments, leak checks, calculations, temperature control, and calibrations. Data is easily transferred to a Microsoft Windows XP-based PC through Ethernet, USB or an optional Wireless Interface.
