Crowborough, UK, 2 May 2012 - Specifically designed for extractive trace analysis applications, the new SERVOTOUGH LaserExact gas analyser from Servomex delivers the exceptional benefits of Tuneable Diode Laser (TDL) Technology within a robust and compact analyser design.
Able to detect a wide range of gases including O2, HCl, HF, NH3, CO, CO2, H2O, H2S, HCN, NO, N2O, CH4 and other hydrocarbons, the LaserExact combines an advanced multipass long path length cell with Servomex's superior High Frequency (HF), Frequency Modulated (FM) signal processing. The result is unsurpassed low ppb detection limits for most gases, making the LaserExact ideal for the measurement of trace gases offline.
The LaserExact's advanced TDL technology delivers a fast response time, highly stable performance and minimal interference from background gases. With no moving parts or consumables, the LaserExact minimises operating costs, while the stable, drift-free performance reduces the downtime incurred by the calibration requirements of other analyser technologies.
The LaserExact utilises advanced peak-locking technology, which eliminates drift over extended operational periods by automatically tracking on the measured gas absorption line or - in applications where the measured gas is not normally present - tracking the absorption line of another gas present in the stream. This robust tracking mechanism ensures a highly accurate operation by the LaserExact over long periods, with calibration frequencies extended beyond twelve months for many applications.
Designed for easy installation and integration, the LaserExact is immediately ready for operation following the connection of power, sample gas and optional purge gas. With gas concentrations provided as 4-20mA outputs with the option of Ethernet communication, the LaserExact delivers immediate class-leading performance that meets ATEX and Class1 Div2 CSA approvals.
The LaserExact is ideal for a wide range of high purity, process and emissions control requirements. Applications include measurement of H2S and CO2 in natural gas, O2 in flare gas recovery systems, trace O2 in glove box applications, corrosive combustion emission gases, and H2S emissions monitoring for biogas, pulp & paper and industrial gas production.
With the LaserExact complementing the capabilities of the SERVOTOUGH LaserCompact short path and SERVOTOUGH LaserSP cross-stack analysers, Servomex now offers the most comprehensive range of TDL gas analysis technology available to the market.
"The potential of TDL technology as an effective and flexible gas analysis technique has been well understood for some time, but the Servomex Laser range enables users to select a specific TDL analyser type optimised for their application," says Chris Cottrell, Managing Director, Servomex.
"By specifically addressing extractive trace analysis applications, the LaserExact brings TDL analysis to a new range of customers."

Our free Webinar on ‘Demystifying the technology and physics associated with gas analysis’ takes place Thursday 16 February 2012, 0800 GMT / 1100 GMT / 1600 GMT.
Tuneable diode laser spectroscopy (TDLS) is a unique analysis method that has widespread use in industrial gas measurements. Diode lasers enable specific detection of gas molecular absorption lines. Although these unique properties provide significant advantages over conventional measurement methods in some applications, there are aspects that affect the accuracy of laser measurements, if not considered properly.
During this webinar Bahram Alizadeh, (Specialist Research Engineer, Servomex) and Karen Gargallo, (Product Specialist TDLS, Servomex) will discuss laser spectroscopy technology with an emphasis on second harmonic wavelength modulation spectroscopy as applied to laser gas analysers. They will also explain the parameters that affect the accuracy of the TDLS gas analysis; such as the effect of window purge (for in-situ installations); line broadening influence of pressure, temperature and background gas composition; and optical interference noise caused by the coherent property of laser light.
Members of the Servomex expert team will be online all day at Servomex’s LinkedIn account at www.linkedin.com/company/servomex for live discussion and feedback.

SERVOTOUGH FluegasExact optimises combustion for major China power plant
Monday, 19 December 2011 00:00
The extensive benefits of the new SERVOTOUGH FluegasExact 2700 gas analyser have produced impressive results for China-based Datang Yangcheng Power Generation Co Ltd.
Datang Yangcheng requested Servomex deliver an analyser solution that would optimise combustion, reduce costs and reduce emissions at the coal-fired plant in Shanxi province, replacing the plant’s conventional zirconia O2 analysers which were unable to provide accurate results.
Datang Yangcheng also wanted to assess the benefits of using CO analysis to reduce boiler fuel consumption, with the hope of improved performance enabling installation of an automated control system to further optimise the combustion process.
Servomex’s Asia Pacific team recommended the use of the FluegasExact, Servomex’s leading fluegas combustion analyser, which uses a patented zirconium oxide cell for O2 measurement and a thick film catalytic sensor to measure carbon monoxide and COe combustibles.
Four FluegasExact analysers were installed in the boilers in the plant’s 660MW units. Positioned between the air preheater and economizer, the FluegasExact’s resilient probe units were installed with an insertion length of two meters to obtain a high speed response and an average flue gas concentration.
After a period of extensive evaluation, the results are extremely positive: the FluegasExact analysers have greatly improved the accuracy and sensitivity of combustion control at Datang Yangcheng. An estimated RMB 6-10m in direct fuel costs will be saved every year for each 660MW furnace, while long-term maintenance costs have been lowered due to reduced corrosion damage in the boilers.
Reductions in NOx, CO and SO3 emissions have been achieved, with the lowering of NOx emissions reducing the quantity and cost of NH3 required for the NOx reduction process. Finally, the risk of flue gas combustion caused by conventional zirconia products has been eliminated, while risk of boiler shutdown when filled with reducing gases and a low O2 level has been greatly reduced.
As the FluegasExact has also been shown to accurately analyse O2 and- COe boilers with little or no maintenance over extended periods of time, it will now be possible to place the system under automatic closed-loop control as per Datang Yangcheng’s requirements – a process currently impossible to perform under manual control.
“The SERVOTOUGH FluegasExact was the ideal solution for fluegas O2 analysis for Datang Yangcheng,” says Frank Zhu, General Manager, Servomex Asia Pacific.
“The FluegasExact has a fast response speed, good measurement accuracy and a high degree of reliability, while avoiding problems common to sampling analysis systems such as high failure rate and high maintenance costs.”

New SERVOTOUGH FluegasExact 2700 delivers the industry-leading solution to combustion analysis
Friday, 29 July 2011 00:00
Building on the success of the acclaimed Fluegas combustion gas analyser, the SERVOTOUGH FluegasExact 2700 integrates Servomex’s unique Flowcube flow sensor technology to give users even more confidence in their combustion gas measurements.
Armed with an integral sampling system, custom-designed for operation in some of the hottest and most extreme combustion environments, the FluegasExact is the analyser of choice for the most demanding hydrocarbon processing and power generation applications.
At the heart of the SERVOTOUGH FluegasExact’s exceptional performance are Servomex’s patented zirconium oxide cell for oxygen measurement and a thick film catalytic sensor for measuring carbon monoxide and COe combustibles.
Able to measure oxygen on a wet basis, the FluegasExact’s advanced zirconia technology requires no external sample conditioning system, while minimal calibration requirements and a long operational life of up to ten years ensure reduced maintenance costs. The FluegasExact’s thick film calorimeter technology monitors CO levels with high precision, giving sufficient sensitivity and speed of response to enable the combustion process to be continuously optimised for increased process safety and efficiency. Combined, the performance of both technologies improves flame stability, reduces NOx, SO3 and CO emissions and has been proven to save up to four percent of fuel costs per year.
Both sensors are installed within Servomex’s custom-designed heated sensor head, which has a low-flow extractive design that attaches directly to the flue. Manufactured to the highest quality standards, this ensures exceptional performance in the toughest environments and with the minimum of maintenance.
The FluegasExact’s exceptional measurement sensor capability is augmented by Servomex’s advanced Flowcube flow sensor technology. Delivering an industry first by enabling true system diagnostics of the sample flow, Flowcube gives total assurance that the measurement is valid and responding within specification. Placed in-line with the measurement sensors, Flowcube allows user-defined alarm levels to be set with confidence, either to enhance preventative maintenance or to act as a flow failure alarm output.
Flowcube technology therefore enables operators to implement a preventative rather than reactive maintenance agenda for analyser flow control, avoiding costly plant downtime by allowing the scheduling of routine safety checks and sample system maintenance – a particularly useful function where operations are being run with minimum personnel on-site.
In addition, a new Sulphur Resistant combustibles sensor enables the thick film sensor to operate at elevated levels of SO2 that normally inhibit catalytic sensors.
Customer-designed for high temperature operation up to 1750°C (3182°F), the FluegasExact is custom-designed for extreme heated environments. This resilience makes it the analyzer of choice for controlling a range of combustion processes used in the hydrocarbon processing and power generation industries, including use in process heaters, utility boilers, thermal crackers, incinerators and furnaces.
