AIR MONITORING Why tyre dust is a hidden risk
Droplet ENVEA Group, recently spoke with Jürgen Gratzl, a PhD researcher in the Physical Chemistry of the Atmosphere group, led by Professor Hinrich Grothe at TU Wien. With growing global concern and increasing evidence around airborne microplastics and their environmental consequences.
Using Droplet’s WIBS (Wideband Integrated Bioaerosol Sensor) analyser in the laboratory, Gratzl is working to better understand how airborne microplastics are formed, transported, and distributed in the atmosphere. The WIBS technology is supporting research that had previously lacked real-time measurement capability, helping to generate new scientific insight that could influence future environmental strategies.
Gas Analyser
UK manufacturer launches new MCERTS approved VOC emissions monitor
Signal Group, a leading UK manufacturer of gas analysers, has announced the launch of SOLAR CEMNEX, a continuous emissions monitoring (CEM) system with MCERTS approval for the measurement of total organic carbon concentration in sample gas. Designed for regulatory compliance and process control, employing a reference method flame ionisation detector (FID), the new analyser will be ideal for monitoring a wide variety of applications. These include incinerators, medium and large combustion plants, VOC abatement equipment, packaging, and solvent using processes such as paint, print, textiles and adhesives.
The SOLAR CEMNEX is a self-contained monitoring system with a rack mounted VOC analyser, a heated filter, heated sample lines, and an automated calibration system.
“We have been developing and manufacturing FID analysers for over 50 years, and the SOLAR CEMNEX is our most advanced system yet,” explains Signal MD, James Clements.
Following a rigorous program of tests at TÜV in Germany, MCERTS approval verifies that the complete monitoring system complies with the performance and uncertainty requirements specified in the UK’s Environment Agency Guidance: MCERTS for stack emissions monitoring equipment at industrial installations - Continuous emissions monitoring systems (CEMS) Updated 28 August 2024, EN 15267- 1:2023, EN15267-2:2023, EN 15267-3:2007 and QAL 1 as defined in EN 14181: 2014. Certification for the SOLAR CEMNEX covers the complete system, including the SOLAR FID analyser, Signal’s heated line and sample probes, and Signal’s 363 SM heated sample filter. Consequently, systems integrators can deploy these items with other MCERTS approved equipment for regulatory compliance monitoring.
The SOLAR CEMNEX can be supplied with a detachable tablet/screen, which allows users to operate the analyser from up to 50 metres away, via inbuilt 802.11 Wi-Fi. In addition, each SOLAR CEMNEX has its own IP address, and is compatible with 3G, 4G, 5G, GPRS, Bluetooth and satellite communications. This provides users with simple and secure access to their analysers at any time, from anywhere. Summarising, James Clements says: “In recent years we have ramped up the development of our gas analysers to enhance their accuracy, simplicity and connectivity, so we are delighted to now add MCERTS approval for those customers with a regulatory requirement.”

Highly accurate air and gas velocity sensor for industrial applications
Developed and designed for demanding industrial applications, the AVS701 from E+E Elektronik sets a new standard in air and gas velocity measurement - proven to last up to 20 times longer in harsh environments. Maximum efficiency and process reliability are ensured through highly accurate measurements, simple installation with an integrated sensor positioning, and a process gas library. The optional external pressure sensor compensates for variations in ambient pressure. Thanks to its robust ceramic sensing element protected by a stainless-steel probe head and a specialised coating, the AVS701 delivers stable measurement results even under corrosive and extreme conditions, significantly reducing downtime and lifecycle costs.
The optically and technically redesigned air and gas velocity sensor excels in accuracy, reliability, and simplified installation. Optimised for demanding industrial
applications with a measurement range from 0 to 40 m/s and temperatures from -40 to +140°C, it is suitable for a wide range of uses – from pharmaceutical production to process monitoring in 3D printing. Efficiency increases in process costs and quicker setup times by 60% make the AVS701 the best choice in its performance class.
The system enables up to 60% quicker sensor setup through accurate sensor positioning and automatically captures the operating flow to ensure reliable measurement results. Efficiency is increased thanks to the highest level of measurement accuracy, while dependable performance is maintained even in the harshest environments, where it has been proven to last up to 20 times longer. In addition, intelligent gas adjustment delivers significant time savings during operation.
“The AVS701 delivers precision and reliability
One of the most significant findings Jürgen Gratzl discussed relates to everyday road traffic: “In high-traffic urban areas or near major roads, the principal contributor of microplastic particles is tyre wear. Tyres contain a high percentage of synthetic polymers. As tyres wear down with use – the materials don’t simply disappear. They end up as tyre dust which contains microplastics that become airborne.”
Jürgen Gratzl adds that a lack of data currently limits our understanding of the sources and scale of microplastic pollution. He also discusses the wider impact on the environment, current gaps in regulations, and how consumers can make conscious decisions to help reduce microplastic pollution.
As global leaders in air quality and emissions monitoring, and with their Droplet WIBS analyser, ENVEA are helping Jürgen Gratzl to research ways to overcome pressing environmental challenges.
Adrien Danner of Droplet ENVEA Group said: “At ENVEA, we are proud to support the scientific community with tools that help to generate insights to address environmental challenges.”
