Flue gas analyzer SM-4

mercuryemissionsautomatic

Total mercury emissions monitor in stack flue gases SM-4 QAL 1 certified for continuous, accurate and reliable measurement of total mercury emissions, even in very low concentrations and within complex matrices (SO2, NOx, HCl, etc.) With over 20 years experience, Mercury Instruments (part of ENVEA Group) were the first to develop mercury monitors and mercury analyzers using a dry thermocatalytic method instead of wet chemistry. The SM-4 Mercury Monitor is QAL1 certified and is ready to meet future regulatory requirements (Minamata convention & European directives for thermal power plants and incinerators). • - 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)
