Combustion Gas Analysis Capabilities Expanded with New Oxygen Probe
ABB Measurement Products (UK) has launched its next generation of combustion gas analysers for industrial and utility boiler applications. Featuring a revised sensor design and an increased choice of probe lengths up to 4 metres (13.12 feet), the Endura AZ20 expands ABB’s offering to a new range of high temperature applications up to 800°C.
A key feature of the Endura AZ20 is its enhanced robust design. Manufactured using a new ceramic-to-steel bonding process, the AZ20 offers improved resistance to thermal stresses and shocks compared to a conventional brazed design. This enables it to be used in a wider range of applications subject to sudden variations in process temperature, as well as offering a gas tight bond throughout its operating temperature range.
The Endura AZ020 benefits from a unique cell processing technique which bonds the multi-layered platinum electrode to the zirconia. This
means that the AZ20 can be used in arduous applications subject to sulphurous and reducing atmospheres such as sulphur recovery processes, crematoria and industrial and clinical waste incineration.
The strength of the AZ20 has been further enhanced by its reduced component count. With fewer parts requiring servicing or replacement, the AZ20 offers simplified maintenance. In the event that problems do occur, the AZ20’s NAMUR compliant diagnostics, with alarms and warnings in clear text, enables operators to quickly trace and rectify the fault.
Operation has been simplified by the use of ABB’s new universal Human Machine Interface (HMI), which has now been extended across its range of instrumentation products. Enabling operators to easily scroll through and select options, the HMI simplifies operation, maintenance and training, reducing cost of ownership and providing a consistent user experience. “Through-the-glass” control technology provides a local operator interface for inputting short, quick data for all user specific parameters without removing the transmitter cover.
As a HART-enabled device, the Endura AZ20 also offers the ability for operators to perform online modification and monitoring of parameters.
Improved process control is ensured by the positioning of the zirconium oxide measuring sensor at the tip of the probe, which is then inserted into the flue duct. This offers the ideal position for direct in-situ measurement, enabling users to get an accurate and immediate oxygen reading for optimizing the combustion control process.
Another new feature is the inclusion of integrated advanced calibration technology, which automatically controls both the test gas flow rate and test gas sequences during calibration
testing. This eliminates the need for expensive ancillary equipment typically needed for traditional flue gas oxygen analyser systems and prevents incorrect calibrations caused by the loss of test gas.

Protea Ltd (UK) is proud to announce that it has recent delivered one of its mobile MCERTS Approved Protir 204 FTIR Analyser Systems to the National Physical Laboratory (NPL).
The instrument will be deployed by NPL’s Environmental Monitoring Group to undertake Compliance and Regularity Monitoring work including QAL2 measurements. The work will be performed in line with the Environment Agency’s M22 Technical Guidance Note on Measuring Stack Gas Emissions using FTIR Instruments.
Richard Camm, Protea’s Managing Director, says that we delighted that NPL chose
the MCERTS Approved Protir 204 mobile FTIR analyser for this application. We know from years of development and experience that this instrument with its high resolution spectrometer and sophisticated PAS chememetric spectral analysis software is ideally suited for these measurements.
Richard also considers that one of the inherent strengths of using the 204M for this category of work is the fixed operation, MCERTS "Combustion" mode software. The NPL instrument was supplied with this enabled, meaning the acquisition parameters and analytical methods are pre-loaded and fixed on their 204M FTIR analyser.
his powerful Combustion Suite Software not only provides a set of analysis methods for the common inorganic combustion gas species, including hydrogen fluoride and ammonia, that are required to be measured under the Waste Incineration Directive, but also a number of organic components are included as well. This means that the instrument is ready to be immediately used after initial training. Any number of further analytical methods can easily be constructed and added by the trained user at a later stage, making the 204M the ideal tool for new and expert FTIR users alike.

IONICON (Austria) launches the new PTR-QMS-300 mobile VOC monitor to the analytics and industrial process monitoring market.
Succeeding the IONICON Compact PTR-MS that has been produced since 2003, the new PTR-QMS 300 is a small and lightweight PTR-MS for research or process monitoring applications with a remarkable detection limit of < 0,3 ppbv.
The PTR-QMS 300 is engineered as a very affordable, user- and maintenance-friendly, lean and innovative bench top set-up that focuses on industrial applications. It features a touchscreen display allowing for one-button control of the system and even preconfigured analysis tasks in combination with an optional embedded industrial computer and individualised software packages.
We provide flexible inlet solutions such as the integrated multi-position capability and the possibility to optionally upgrade the PTR-QMS 300 with multiplexing and data interface units thus bringing down the costs per sampling point and simplifying the integration in existing monitoring network infrastructure.
For research or laboratory use the PTR-QMS 300 is available as a fully functional entry- level PTR-MS instrument, being operated using the comprehensive IONICON PTR-QMS series software suite, available on an external notebook computer.
