Tekran Instruments Corporation

- Model 3300Xi HgCEM - Mercury Continuous Emissions Monitor - Mercury CEM - Flue Gas Analysis - Emissions Analyzer



The EPA Electric Generating Unit Mercury and Air Toxics (EGU MATS) and Portland Cement Maximum Achievable Control Technology (PC MACT) regulations require reductions in gaseous mercury emissions. Tekran has proven technology to support mercury compliance monitoring, abatement system optimization, and performance audit testing instrumentation.

Air Pollution Control Equipment: Performance Guarantees and Acceptance Testing

Architect engineers, consultants, and end users are seeking validation of mercury abatement technologies including, but not limited to:

  • Pre-combustion chemical additives
  • Post-combustion treatment
  • Mercury oxidizing technologies
  • Wet scrubber additives
  • Custom mist eliminators

Current specifications requiring performance guarantees may be challenging to comply with:

  • Inlet/outlet conditions are ill-defined
  • Sorbent trap systems may over estimate gaseous Hg

Tekran is the only company providing all the following:

  • Ten years of HgCEMS design, manufacture, and service support
  • Multi-point HgCEMS sampling technology for inlet/outlet testing
  • NIST Traceability ¡V Tekran 3310 low and high level generators used by NIST
  • Low-level measurements certifications of accuracy (EPRI, EERC, CATM, ICCI)
  • Service personnel average 10,000 hours of field and laboratory experience
  • Parts, training, and support by phone, email and remote access

Electronics Platform

  • Network enabled
  • Touch screen interface
  • Local data storage and front panel USB port
  • Remote access (troubleshooting, control and configuration)
  • Improved data and instrument parameter logging
  • Additional functionality via optional s/w plugins (std. additions, remote valve control, and much more)


  • New lamp stabilizer and detector electronics
  • Easy cuvette removal via convenient fitting interface
  • Improved stability and sensitivity
  • Digital PMT control and display

Permeation Source

  • Lower dead volume permeation chamber
  • Digital permeation source set point and display
  • Improved accessability

Cartridge / Valve Assembly

  • New low dead volume valve assembly
  • Constant power heater control
  • Faster cartridge cool down with individual high-velocity fans

Physical Layout

  • Reduced height from 5U (8.75”) to 4U (7”)
  • Improved component accessibility for routine maintenance

Building on over twenty years of experience in mercury measurement, Tekran has leapt to the forefront of the Mercury CEM industry by leveraging our experience with cold vapor atomic fluorescence and pure gold pre-concentration. In reliability, system availability and analytical accuracy, the Tekran Series 3300 systems have outperformed all competitors in EPA and private tests in wet and dry stacks. The Series 3300 can measure total, elemental and ionic mercury in virtually any combustion source. The system is sensitive enough to measure levels at any coal fired power plant and is immune to the interferences that plague conventional mercury CEMs.

Key Features:

  • Patented mercury speciation technology to determine elemental, ionic and total mercury
  • Unaffected by SO2, NOX, CO, HCl and all other common combustion by-products
  • Interfering acid gases removed without chemical reagents or solid sorbents
  • Provides real-time feedback for mercury control technology optimization
  • Detection limit less than 0.05 ug/m3, with rapid response time
  • Low-cost calibration eliminates expensive mercury calibration gas cylinders
  • No chemical reagents required
