The Smogmobile helps educate primary school children on the dangers of air pollution at Mums for Lungs Clean Air Carnival 2023

ET’s air quality monitoring laboratory - The Smogmobile ( was out at last weeks (8th June 2023) Clean Air Carnival in Lambeth, London doing what it does best, showing off its fantastic array of sophisticated air quality monitoring technology for children and adults alike to see it working in practice, producing real-time data on the quality of the air we breathe.

The Mums for Lungs organised event was well received with a large number of local children taking to the streets to learn about the importance of clean air for our minds, bodies and the environment.

ET MD, Duncan Mounsor, attended the event as a STEM ambassador along with some academics from some of the most prestigious scientific organisations in the UK. The event benefitted from the presence of Dr Ian Mudway, Senior Lecturer in the School of Public Health at Imperial College, London and Dr Rosamund Dove a postdoctoral Researcher at The Queen Mary University of London and member of Children’s Health in London and Luton (CHILL).

Duncan, who is passionate about educating the next generation on the dangers of air pollution, commented on the event “As a STEM ambassador I find these types of community outreach events are great opportunities to engage with primary school-aged children. At the carnival It was great to see such a large number of young people really interested in learning about air quality and how it is measured by instruments such as those utilised in our fully electric, Smogmobile.

As a company, we really value opportunities such as this to talk to the public, in particular the younger members, about the wide-reaching effects of pollution. It helps towards influencing a more considered mindset when it comes to making everyday choices about how our actions can affect environmental issues such as air pollution. “

ET’s Smogmobile will take a short rest now until Clean Air Day on June 15th when it will be zooming down the M4 to Newport to monitor and raise awareness in South Wales.

ET supplied Microportable Greenhouse Gas Analyser enables Somerset Wildlife Trust to monitor CO2 and CH4 emissions from Somerset’s Lowland Peatlands.

Beth Pudifoot at Honeygar Farm Somerset

Over the course of the past year Somerset Wildlife Trust along with partners at Avon Wildlife Trust, RSPB and Natural England have investigated the greenhouse gas (GHG) emissions from Somerset’s lowland peatlands. 

Lewis John, ET’s Sales Manager for Scientific Applications, met with Somerset Wildlife Trusts Peatland Partnership Greenhouse Gas Monitoring Officer, Beth Pudifoot at Honeygar Farm recently to see first-hand how the ABB LGR-ICOS GLA-1313-GGA Microportable Greenhouse Gas Analyser, supplied by ET, was used for this project.

Investigations showed how a broad baseline of GHG emissions from different peatland land use types in Somerset, might be affected by different land management actions such as cutting and grazing.

Beth Pudifoot comments “We found the GLA131-GGA very simple and user-friendly, particularly the associated real-time interface. The smaller size meant it was convenient to transport and carry across site. It consistently produced good quality, reliable data, which along with quick and detailed support and assistance from ET, meant the GLA131-GGA was ideal for use in our project”.

Samples were taken on 11 different sites, with a combination of land owned by nature conservation organisations and privately owned agricultural land being monitored. Overall, the project evidenced that between May and December 2022, the Somerset Levels and Moors were a constant source of carbon, with levels ranging from a monthly average of 0.24 – 1.75 g/m2/hr CO2e.

The project focussed on engaging with local landowners and managers, without who’s buy-in and collaboration success wouldn’t have been assured.

The results highlighted the importance of protecting peatland ecosystems, especially in the face of climate change. The project also reinforced that there are potential emission reductions to be made, transforming this landscape from net emissions to net sequestration.


Somerset Wildlife Trust has ambitions to continue the monitoring of GHGs across the Somerset Levels and Moors into the future, building on the baselines recorded this year.

Keep a look out for the full Case Study which will be published soon!

ET team up with Fife Council on Clean Air Day to educate future generations.

The Smogmobile at St Margaret's primary School in Fife

Clean Air Day (CAD) is the UK’s largest air pollution campaign, bringing together communities, businesses, schools, and the health sector.

Back in September 2021, ET agreed the hire of the Smogmobile to Fife Council to assist with their campaign to highlight the dangers of air pollution and to try and increase active travel to and from Schools to run for the three days up to CAD 2022 (June 16th).

The Councils objective was to raise awareness of air pollution levels peaking at drop-off and collection, and exposing children to harmful toxins and to encourage walking, cycling or scooting to school as a healthier alternative.

Over the three days, ET’s Managing Director, Duncan Mounsor, monitored air pollution at three primary schools around Dunfermline using ET’s custom-made mobile air quality monitoring laboratory - the Smogmobile.

Duncan, who spoke to 15 groups of children during one of the days commented: “I actually get a huge amount of job satisfaction visiting schools to talk about the dangers of poor air quality. It’s a global problem. We must educate ourselves and our children to help ensure we continue to decrease pollution levels for future generations”

Blair Falconer, Fife Council’s Land and Air Quality Technician said “The project was key in raising awareness among local children. We hope we have inspired some changes, and that the children continue to build upon this knowledge”.

During the visits, the children were excited to see the mobile laboratory in action and had lots of questions. Teacher, Isla Ferguson remarked, “The pupils at Carnegie Primary have been buzzing about Clean Air and monitoring air pollution all week! I've had some lovely comments from a couple of parents saying that their children - who were involved in some of the many groups who came to listen to Duncan - found it really fascinating. Once again, thanks for the opportunity to be involved: our students have really benefitted.“

The Smogmobile really lends itself to this kind of research and education project.

The Smogmobile’s next outing is to Westminster on June 28th where it will be monitoring at two Westminster locations to mark London Climate Action week. Smogmobile visits Westminster for London Climate Action Week | Westminster City Council

ET Scientific application specialist travels to Stellenbosch University to train scientists on the ABB / LGR Triple Liquid Water Isotope Analyser.

Lewis John training Dr. Janine Colling and Volante Moonsamy at Stellenbosch University

It’s not often any of our Sales team get to go to such a scenic location to train a customer on one of our products but on this occasion, they certainly did!

ET’s Scientific Applications Sales Manager, Lewis John and MD, Duncan Mounsor set off for sunny South Africa in early April this year following an order for an ABB / LGR Triple Liquid Water Isotope Analyser from BIOGRIP (Biogeochemistry Research Infrastructure Platform) at Stellenbosch University.

The BIOGRIP facility at the university provides access to advanced analytical techniques and instruments for water and soil research to clients in industry and research institutions. It also provides post-graduate students the opportunity to be trained to operate the equipment.

Lewis trained Dr. Janine Colling, a scientist based at the University and Volante Moonsamy, Junior Analyst at BIOGRIP over the three days he was there.

Dr. Janine Colling, Lewis John, Volante Moonsamy and PHD student
Their procurement of the TLWIA is a significant development in water isotope research. The vast majority of existing research in this area has been done in the Northern hemisphere, so there are many unknowns with regards to isotopic compositions and transport mechanisms in the Southern hemisphere water cycle, and lots of novel research to be done. Janine is one of very few researchers in SA to have access to a water isotope analyser that can measure δ17O, this is due to the advantage of the unique Off-Axis ICOS cavity design.

The TLWIA will be available for internal research, but also for Masters / PhD student projects, and commercial analysis for clients along with other high-end isotope instruments in their new laboratory.

The TLWIA will be a profitable tool for Stellenbosch University, with its low running costs, minimal need for maintenance, and high rate of sample throughput. These are specific advantages to the LGR TLWIA that make it a very desirable acquisition for commercial laboratories and research institutes alike.

CASE STUDY - Auchencorth Moss Atmospheric Observatory, Scotland.

It’s not often we can claim to have supplied samplers to such a scenic location, but in this instance, we certainly can.

The picturesque landscape (shown below) is home to one of the UK’s most significant research facilities for the study of long-term environmental change.

About the site

Auchencorth Moss Atmospheric Observatory (AMo) is a long-term monitoring research infrastructure situated on ombrotrophic peatland based approximately 18km south of Edinburgh. Consisting of 10km2 of patchy mix of grasses and sedges, it lies on a base layer of typical peatland.

Its purpose is to carry out research on long-term atmospheric composition, surface-atmosphere exchange of pollutants and carbon catchments. As a result of the large number of parameters that are routinely measured at the site, it is part of a wide range of monitoring networks.

Originally (1994) the site was used to study methane fluxes, the following year studies expanded to include sulphur dioxide and ammonia fluxes due to its peatland ecosystem and distance from emission sources. It has since developed into Scotland’s largest Air Quality Monitoring station being one of only two rural supersites in the UK.

Today AMo reports over 300 chemical and physical properties of the atmosphere and is used as a platform for many research projects operated by UKCEH Scientists, with all data publicly available on the UK-Air (DEFRA), Scottish Air Quality database, Natural Environment Research Council Data Repository for Atmospheric Science and Earth Observation (CEDA) and EBAS (

Monitoring equipment

With such a large scope of research depending on the site it’s no surprise it’s equipped with state-of-the-art monitoring technology. ET supplied the site with Digitel High Volume (below left) and Low Volume Samplers (below right) over a period of time from 2011 to 2022.

AMo Instruments

These sophisticated instruments are ideal for this kind of work. The HVS DHA-80 samplers have an autonomous system for continuous sampling of dust and aerosol particles for later assessment and analysis. Air-borne dust particles in the sampled air are separated on to Ø 150 mm filters so that sequent gravimetric and analytical analysis can be conducted, depending upon the pollutants of interest. The filters are subject to a constant and precise volume flow and are changed automatically at pre-set intervals.

The LVS DPA14 uses a similar operation, but its execution is 5 to 50 litres per minute (0.3 to 3m³/h as opposed to the 100 - 1000 l/min (6 - 60 m3/h) capacity of the HVS system.

It’s the superior workmanship in sampler mechanics, backed by the latest technical and electronic control, that guarantees a long lifetime and absolutely reliable operation of these units. And their involvement at facilities such as AMo is a testament to that.

In addition to the samplers, over the years ET have supplied other high specification instruments to AMo including a Teledyne API T200UP Ultra Sensitive Chemiluminescence Analyser with patented high efficiency Blue Light Converter (BLC) in 2016. The BLC provides a very specific conversion of NO2 with conversion efficiency, avoiding the interferences other methods would be affected by. This allows for consistent and accurate NO2 measurements.
