Description

Mercury Instruments (ENVEA Group) has developed the SM-4 analyzer specifically for total mercury emission monitoring applications in order to measure very low levels of mercury in flue gases as well as complex matrices (SO2, NOx, HCl, etc.) with high accuracy and reliability

Dry thermocatalytic method: no need for reagents, water refills or solid reagent cartridge replacements.
Sample dilution eliminates interference from matrix gases such as SO2, NOx, and HCl, etc. the system being able to measure with virtually any sample matrix
Maintenance free converter directly at stack: no transport of ionic mercury thus minimizing mercury adsorption
- Thermo-catalytic converter principle operating at low temperature
- Detects elemental, ionic and bound mercury
- Mercury speciation available (as an option)
- Automatic QAL3 as an option
- Very low maintenance (average service interval: 3 months) – can be automated
Also exists in a transportable version: Easy to transport, assemble & dismount. Ideal for the determination of total vapor phase Hg emissions at varying measuring points & sites (especially for the control of Hg reduction systems efficiency)
Approved and certified by TÜV Rheinland (QAL1), compliant with US EPA 40CFR60 PS-12A Mercury CEMS
