CMM Continuous Mercury Monitoring System

Gasmet CMM is a complete emission monitoring system designed to meet the regulations for continuous mercury measurement standards in different combustion sources, such as coal fired power plants or waste incinerators. Relying on proven technologies it is a robust, reliable, and cost-effective measurement system to meet the latest standards. The system has low need for maintenance and provides an excellent solution for demanding industrial measurement conditions like other Gasmet analysers.

Gasmet CMM employs atomic fluorescence spectroscopy and thermal conversion of ionic mercury compounds to atomic mercury. It measures hot, wet and corrosive gas streams. No wet chemistry or gold amalgamation trap is needed. High inherent sensitivity of the atomic fluorescence spectroscopy enables extensive dilution of the sample gas. The diluted sample gas is transported to the analyser. Directly after thermal reduction of the mercury compounds the dry gas containing only atomic mercury is lead to the sample cell. Calibration of the whole system is performed with an automatic calibration unit capable of producing constant flow of atomic and (as an option) oxidised mercury.
