Air Monitoring Improved Ambient Air Gas Analysers
The Ecotech (Australia) Serinus ambient air gas analysers continue to evolve with improved appearance, functionality and performance. Offering improvements in communication, programmability and useability, Ecotech's latest upgrade to the Serinus analysers provides a solution that is second to none for use in ambient air monitoring.
The Serinus analysers are U.S. EPA Equivalent or Reference Methods and EN approved. They are designed especially for the measurement of criteria pollutants including O3, CO, NO/NO2/NOX and SO2. Additional instruments in the range for the measurement of NH3, H2S, TRS and TS are also available.
The Serinus range features enhanced communication which now includes RS232, USB and Bluetooth as standard plus optional TCP/IP ethernet. Bluetooth connectivity combined with the “Ecotech Serinus Remote” Android App (available from the Google Play store) makes it even easier to program, maintain, download and email data without touching the instrument.
Completing our communications package is a wide range of protocols including Modbus, Bavarian and Ecotech’s own advanced protocol which provides access to over 200 measurement and diagnostic parameters.
Combining these analysers into an ambient monitoring station and using Ecotech’s Airodis Data collection, validation and reporting software to manage data helps our customers achieve high data capture rates, minimise maintenance and achieve their air quality monitoring objectives.

NOthing compares with NOx
The CLD 811 nitrogen oxide analyser is unique in its performance. It allows the measurement of NOx concentrations in raw exhaust of several thousand ppm down to a few ppb.
Nowhere else are the demands for response time, sensitivity and reproducibility in analytical instrumentation as tough as in the engine business. The CLD 811 fulfills exactly these requirements. The unmatched dynamic range combined with the unique linearity of the chemiluminescence principle cope with the basic demands. With its heated inlet and its automated pressure control the instrument handles not only your rough samples such as hot and humid exhaust gases but also diluted samples from bags. This is the result of an extended range capability designed into this state of the art NOx monitor.

The advantage of compact design: The CLD 811 includes everything in one case – even the vacuum pump and the ozone scrubber. It saves space in your cabinet and simplifies your test bench design. The use of first-rate components guarantees virtually service- free operation. Maintenance simply means annual replacement of filters and membranes besides the consumables required by special sampling conditions. With such a minimal maintenance effort you will enjoy the operation of your instrument for years.
An ECO PHYSICS (Switzerland) analyser is always developed with full user comfort in mind. It can be operated by means of the integrated touch screen or remotely from a personal computer. The clear layout of the menu structure guides the user and enables him to take advantage of all analyser functions with simple commands. And with the standard AK protocol you get what you need.

25991pr@reply-direct.com New Mercury Emissions Monitor Launched
Gasmet (Finland) will launch a new continuous mercury monitoring system (CMM) for stack emissions at Mercury 2013. Offering very low detection limits without interferences, the Gasmet CMM is simple to operate, with lower operational costs than other systems.
Gasmet Europe’s Antti Heikkilä says “The CMM employs cold vapour atomic fluorescence (CVAF) to deliver very low detection limits at a significantly lower cost than other comparable mercury monitoring instruments.
“We have already installed systems in Finland and Poland, and initial users have been delighted with the CMM’s ability to measure low Mercury levels without cross-interference from gases such as Sulphur Dioxide. No separate chemicals, gold amalgamation concentrators, air scrubbers or additional gases are required, so operational costs are also very low.”
Legislation to limit mercury emissions from combustion processes is progressing quickly in many parts of the world, but process managers have already started to implement mercury monitoring programs. Antti says “We have received enquiries from companies that need to prepare for compliance by better understanding their mercury emissions. However, we are also being contacted by process managers, for example from Sulfuric Acid manufacturing plants, who wish to control Mercury; not just in their emissions, but also in the end-product, by measuring directly in the process stream itself.”
The CVAF spectrometer has an integrated high temperature converter to effectively transform mercury compounds to atomic mercury without any chemicals or vulnerable catalyst materials. The close coupling of converter and fluorescence cell also ensures that Mercury does not recombine to, for example, Mercury Chloride between the converter and the Mercury Analyser. Sample gas dilution with synthetic nitrogen generated within the CMM system is an effective tool to promote sample transportation whilst
decreasing the loss of Hg0 fluorescence signal to interactions with O2, CO2, and H2O. The fluorescence cell is specially designed to eliminate stray reflections and background light so that even with sample dilution the CMM system is capable of monitoring low levels of mercury as required in the forthcoming US Clean Air Mercury Rule.
The system is controlled through a touch screen control panel, which is integrated with the analyser and calibrator inside an air- conditioned cabinet, and calibration is maintained with regular automatic zero and span calibrations using Hg0 and HgCl2 calibration gases generated within the CMM system - typically every
24 hours. Periodic linearity checks with atomic mercury or mercury chloride are also possible.
The Gasmet CMM is now available from a worldwide network of subsidiaries and distributors; however visitors to Mercury 2013 (
www.mercury2013.com Edinburgh, Scotland, 28th July – 2nd August) will be able to meet some of the Gasmet staff that have been involved in the development of this technology at stand No. 24.
