Gasmet™ CMM Datasheet - 25815 Why Should You Settle for Less?

With the introduction

of ever tightening legislation for emissions, new challenges are also facing the equipment that is used for continuous monitoring of trace pollutants. In the United States, the Clean Air Mercury Rule will establish strict limits for Mercury emissions from coal-fi red power plants. It’s essential that the Continuous Emissions Monitoring System not only provides accurate and reproducible results, but is also able to operate under extended periods of time with minimum need for maintenance. Right from the beginning of the R&D process, the Gasmet™ CMM has been designed to exceed the requirements of U.S. EPA PS-12A and / or Part 75 provisions. For example, all system components which are in contact with the sample gas are made of inert materials.
2 and HCl, CVAF is free from interference from these gases. In addition, the exceptional sensitivity of CVAF to Hg allows dilution of the sample gas, avoiding many of the problems that are commonly associated with sample treatment systems. The result of this joint effort is the Gasmet™ CMM (Continuous Mercury Monitor), which relies on the Cold Vapor Atomic Fluorescence technology (CVAF). Whereas traditional mercury CEMS have relied on technology such as Atomic Absorption Spectroscopy, which is susceptible to interference from other compounds such as SO
* decided to meet this challenge with a novel approach together with the Technical Research Centre of Finland (VTT).
** The goal of the project was to design an analyzer system that would incorporate the latest technical advances in both analytical methods and stack gas sampling. Also, latest standards and regulations were taken into account already at the design phase of the system.
*) Gasmet Technologies has been leading the way in bringing the advanced FTIR – measurement technology to on-line process applications, such as continuous emissions monitoring in waste incinerators & cement kilns. With more than 1000 Gasmet™ analyzers supplied to date, Gasmet Technologies is committed to provide our customers with the best possible support through our extensive network of representatives. www.gasmet.fi **) VTT Technical Research Centre of Finland is the biggest multi-disciplinary research organization in Northern Europe.
