Environmental Monitoring Solutions
Perfectly adapted to monitor the efficiency of different Mercury Removal Units (MRUs) in natural gas processing plants.
Each mercury online system will differ in sample characteristics as well as installation conditions and operating environment. We have the experience to design systems that fully meet the requirements of your particular mercury monitoring task.

Measuring of Total Gaseous Mercury (TGM) in air and other gases. Reliable for measurements at ultra-trace levels (sub-ng/m³) according to EN 15852 . The UT-3000 operates automatically. All functions are controlled by an embedded microprocessor. When measurements are carried out, all parameters and results are stored in the integrated data logger. With standard settings the data logger has a recording capacity of 5000 measurements (approx. 2 months).

The mercury analyzer PA-2 is used for continuous monitoring of mercury concentrations in industrial processes. The PA-2 was specially designed for process analysis and operation under harsh industrial condition.
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).
The LabAnalyzer is the perfect solution for quantitative determination of mercury in aqueous samples and sample digests in the laboratory. In contrast to a typical multi-element AAS the LabAnalyzer 254 is specially designed for elemental mercury. This allows top performance in analytical applications. The use of a specially developed highly stable mercury lamp in connection with thermostat-controlled UV sensors results in a detection limit of a few ppt of mercury.
