- Automatic and continuous monitoring of total mercury emissions in stack flue gases. QAL 1 certified
- Extremely high precision and reliable measurement
- Automatic back-flush function
- Continuous measurement of total Hg (elementary, ionic & organic)
- No liquid waste or condensate generated
- Sample dilution directly at sampling point, allowing for large measuring range & elimination of interferences from matrix gases, no transport of ionic Hg
- Sampling system – composed of the probe, the dilution unit and the low temperature catalytic converter – is entirely heated to avoid mercury adsorption
- Very low maintenance (service interval: ≥ 3 months) – can be automated
- Ultra high sensitivity: low measuring range is 0.05 µg/m3
- Approved and certified by TÜV Rheinland (QAL1)
- Main options:
- Mercury speciation
- Elemental Hg calibration gas generator NIST traceable, installed inside the analyzer cabinet
- Automatic calibration systems (oxidized and elemental)
- Automatic QAL3
- Sampling line length up to 100 m (300 ft)
- Coal fired power plants (before & after mercury absorbers)
- Emissions monitoring for facilities under 13. and 17. BImSchV
- Cement kilns
- Sulfuric acid producing foundries
- Waste Incineration plants (industrial, medical waste, sewage sludge…)
- Thermal treatment of contaminated soils, hazardous waste
- Metallurgical facilities with potential Hg emissions…
