Ever wondered how the monitoring of NO2 has evolved over the years?

ET are hosting a webinar on August 6th at 2:30pm which will explain the various techniques that have been used over time as well as the cutting-edge technology that is now available.

In this webinar, Enviro Technology’s Managing Director, Duncan Mounsor, and UK Sales Manager for Scientific Applications, Lewis John, will discuss the monitoring of nitrogen dioxide (NO2).

The presenters will describe NO2 as a pollutant, how it is produced, and its atmospheric chemistry, before discussing NO2 monitoring in detail. The reference technique of chemiluminescence and its evolution through the decades will be explained, and then contrasted with alternative techniques such as Cavity Attenuated Phase Shift Spectroscopy (as used in the Teledyne-API T500U and N500), and DOAS (as used in the AirYX ICAD analyser and Opsis open path systems).

This webinar should help attendees gain a deeper understanding of the atmospheric characteristics of NO2, the considerations that should be taken when monitoring NO2, and the variety of instruments and techniques available from ET for monitoring NO2

Registration will be open soon!

The NEW large footprint Soil Gas Flux Chambers that are designed for accuracy.

Enviro Technology Services are pleased to add the new, large footprint eosAC-LT (transparent) and eosAC-LO (opaque) Automated Soil Flux Chambers from Eosense to its portfolio of soil gas flux measurement instruments.

The field ready design of the eosAC-LT/LO allows researchers to capture variability related hot spots and hot moments for trace gases including CH4 and N2O using the automated closed dynamic chamber technique. With the high resolution provided by a compatible analyser, even the smallest changes in gas flux can be captured.

Simple set up and integration

With a remarkably simple setup process you can be up and running in a matter of minutes. Each chamber has a reach of 30m from the analyser giving a potential total coverage area of 2800m2. If paired with the eosMX or eosMX-P multiplexer, users can connect up to 12 eosAC-LT/LO chambers to their ABB-LGR analyser for continuous measurement of multi-species gases including CO2, CH4 and N2O.

EosACLTLO chamber

Additional Sensors

Additional sensors can be added via the chambers two auxiliary ports to enable PAR, soil temp and moisture data to also be collected. The eosAnalyze –AC software will process the data via any Windows based PC or device.

Field Replaceable Components

Reliability is key to any field study, so all critical components of the eosAC-LT/LO have been designed for replacement with minimal effort out at site thus reducing downtime and the resulting data loss.

Potential Applications Include:

  • Net Ecosystem Exchange(NEE) CO2 Flux
  • Agricultural N2O Emissions
  • Wetland CH4 Emissions

ET’s UK Sales Manager for Scientific Applications, Lewis John, comments..

“Enviro Technology has been working with Eosense for several years, and we have always been impressed by their innovative and “hands-on” approach to developing soil flux measurement products.

Eosense’s original, smaller eosAC chambers have been very popular as they include several features to simplify soil flux measurements for the user, including automatic flux calculation software, a vent design to reduce pressure differentials, and a stepper motor to raise and lower the chamber slowly without disturbing the ground. These new chambers complement the existing Eosense range by catering to those who need transparent and opaque chambers for photosynthesis experiments, as well as those who simply need a larger chamber to take measurements of a wider area (or plant).

Just like the original eosAC chambers, the eosAC-LT and eosAC-LO are fully automated, and fully compatible with our range of ABB-LGR greenhouse gas analysers!”

Measure more than just PM10 and PM2.5 with the GRIMM 11-D & MiniWRAS

GRIMM Aerosol Technik manufacture a vast range of instruments for measuring particulate matter, ranging from environmental PM10 & PM2.5 monitors to butanol CPCs suitable for measuring nanoparticles. Enviro Technology has been a partner of GRIMM for many years, and we have supplied numerous EDM-180 environmental dust monitors in our time as a GRIMM agent. More recently we have expanded our catalogue to include GRIMM’s excellent Nano and IAQ product ranges. The two products highlighted in this article showcase the versatility of GRIMM’s technology, and the fact that GRIMM can do much more than just measure PM10 and PM2.5!

The GRIMM 11-D Portable Dust Decoder is a very compact, battery operated instrument using the same total inlet flow 90° laser scatter detection method as the well-established GRIMM EDM-180. The 11-D can measure TSP, PM10, PM4, PM2.5, PM1, and PMcoarse­ using the “Enviro” algorithm, or pm10, pm2.5, pm1, inhalable, thoracic, and respirable dust in “IAQ” mode. In addition to all of these parameters, the 11-D also measures particle number distribution in 31 equidistant size channels, from 0.253 right up to 35.15 μm! Additional features include an internal filter for post-analysis of collected dust, and a flow of sheath air which prevents dust from contaminating the optics.

The GRIMM 1371 MiniWRAS expands on the capabilities of the highly popular 11-D by enabling the measurement of nanoparticles. Like the 11-D, the MiniWRAS is a portable, battery operated instrument with a flow of sheath air to protect the optics. Not only is the MiniWRAS capable of measuring PM10, PM2.5, PM1, and particle size distribution over 31 size channels using the 90° laser scatter module from the 11-D, it also includes a Faraday Cup Electrometer. The FCE provides an additional 10 size channels from 10 – 193 nm, providing a total size range of 10 nm – 35 μm, hence the name Mini Wide-Range Aerosol Spectrometer!

For more information about the 11-D Portable Dust Decoder, 1371 MiniWRAS or any of Grimm Aerosols range of products for environmental dust monitoring within the UK and Ireland, speak to one our specialists today.

Enviro Technology Services collaborates with supplier EarthSense, to improve Calibration Efficiency with New Reference Station at Zephyr® Manufacturing Site

ET and trusted partner EarthSense, have worked together to install an air quality reference site at the Zephyr® manufacturing facility in Derby to boost efficiency and scalability of sensor distribution.

The latest reference station improves productivity as units are manufactured and instantly deployed for calibration and validation at a single location, avoiding any unnecessary journeys through previous reference points and further improving the pace of deliveries to Zephyr® users. Users can now receive and install sensors to measure near government standard air quality data at a faster rate.

Zephyr 8

ET has constructed the reference site with a high specification data logger that records measurements of gases and particulates such as nitrogen dioxide (NO2), ozone (O3) and particulate matter (PM2.5 and PM10) every 10 seconds, with data transmitted to EarthSense servers every hour. Measurements ensure calibrated Zephyr® sensors are providing reliable, validated air quality data before being sent to users around the world.

Paul Norman, UK Sales Manager at ET, said: “Working alongside EarthSense to establish a reference station at the Zephyr® manufacturing site has demonstrated innovative ways in which we can help to provide trustworthy air pollution information. Not many other low-cost sensors have their own reference site that permits units to be regulated as efficiently as Zephyr® sensors.

“We’ve made certain to include additional room within the enclosure to provide more reference instrumentation as sensor capability expands. We’re confident that as air quality sensing evolves, we can ensure the provision of additional measurements for EarthSense sensors.”

Dr. Roland Leigh, EarthSense Technical Director, said: “We identified an opportunity to construct a reference site at the Midlands-based manufacturing facility and provided ET with parameters for a personal bespoke enclosure. Enviro Technology built a 2m2 enclosure exclusively for our Zephyr® sensors.

“We are fortunate to be able to work with companies like ET as it means we have the privilege of providing stakeholders with the relevant resources to accumulate the most efficient, highest quality air pollution data. We’re always on the lookout for ways in which we can improve our air quality measurements for our customers,” continued Leigh.

The Industrial Emissions Directive (IED) states that by November 2023 there will be a legal requirement to have an online continuous emissions capability to measure total mercury.

ET can help you meet the new legal requirements for monitoring Mercury.

Stroud based environmental company build the world’s first Ecobrick air quality monitoring station.

Enviro Technology Services Ltd (ET), who supply anything from single gas analysers through to large sophisticated air quality monitoring stations for a global market have a strong ethical belief in protecting the environment and recognises that sometimes unconventional ideas can achieve great results.

Located in Stroud, Gloucestershire (a town widely acknowledged as being one of the greenest in the country), ET’s CSR committee decided to challenge the company to go the extra mile when it came to recycling and reusing by producing ecobricks as a way of preventing single use plastics, originating from their head office, going into landfill.

Up and down the UK there are local ecobrick community groups all collecting the densely packed plastic bottles for use in community projects and perhaps not surprisingly, Stroud has a particularly large, active and passionate ecobrick group.

Running to work one morning earlier this year, ET’s MD Duncan Mounsor had a bright idea.

His idea was to build an air quality monitoring station, nothing new to ET, but making it using plastic waste from the local community in the form of ecobricks.

After making contact with Stroud ecobrick group, who were delighted with the idea, plans were set in motion and 400 ecobricks that had been filled by the local community were delivered to ET.

As Duncan explains “At ET we recognise our corporate and social responsibilities not only to our customers, suppliers and employees but also the impacts that we make on society, the economy and the planet. We try to make a positive difference, not only in our local community but in other locations in which we operate”.

Duncan continues: “The idea behind building an air quality monitoring station utilising ecobricks seemed like a great solution to demonstrate how we can all think outside of the box in terms of how to do things differently to benefit the environment whilst simultaneously achieving a great result in terms of product design”

The AQ station framework itself was built using Skokbord, a material made from 100% recycled plastic and wood from Bristol Wood Recycling Project. Duncan comments: “It was important to us to make sure the majority of the materials used were recycled and not just the ecobricks themselves.”

Duncan concludes: “Our projects team did a fantastic job turning my crazy idea into reality and we are all very proud of our accomplishment. I tend to think of it more as a piece of urban modern art than a roadside air quality monitoring enclosure and I don’t think it would look at all out of place in the Tate Modern!”.

Methane measurement made easy with the newest range of microportable greenhouse gas analysers

Specialists in the world of high precision, portable gas analysers, ABB / Los Gatos Research, have gone and done it again with the MGGA- 918 series. Their latest, lightest ever, microportable greenhouse gas analysers the M-GGA-918 and M-GPC-918 weigh little more than a third of the weight of the original ultraportable greenhouse gas analyser (UGGA), clocking in at a svelte 5.8 kg and yet delivering highly reliable data suitable for reporting fugitive emission measurements of methane (CH), carbon dioxide (CO) and water vapour (H20) simultaneously.

With a crushproof case and three-hour internal battery, the 918’s are simply one of the most convenient field instruments available on the market today. Ideal for compliance monitoring, leak detection (e.g., natural gas, coal seam gas, coal bed methane), air quality studies and soil flux studies.

Additionally, there’s no need to wait, data is recorded just 20 seconds after switch on. The internal computer stores data practically indefinitely on a SD card and send data to a tablet, smart phone or other Wi-Fi device.

The M-GGA-918 includes an “Extended Range” option which allows accurate methane measurements at % level (without dilution) without reducing precision and sensitivity at typical ambient levels - a unique capability.

The M-GPC-918 provides an extended range option up to 1000 ppm.

It really is possible to have laboratory standard analysis that is easy to use at your fingertips anytime, anywhere.

Working together to deliver the highest quality scientific instrumentation for academic research.

ET have been distributors for the Los Gatos Research (a member of the ABB Group) since 2012. Suppliers to the UK and Ireland of their range of rack mounted trace gas, ultra-portable and Isotopic gas analysers.

Enviro Technology and Airmodus work together again in the UK to provide researchers with best-in-class ultrafine and nano-particle counting solutions. 

Enviro Technology (ET) is delighted to be working once again with the world-leading Finnish nano-particle counting technology expert, Airmodus. When ET and Airmodus last worked together in 2012, it is fair to say that that many researchers just didn’t think it was possible to accurately and reliably count particles smaller than the detection threshold of CPC’s, especially in the 1-4 nm size range.

There has always been strong academic interest in these, the ‘smallest of the small’ particles, and Finland has established itself as one of the World’s leading research centres of excellence in this area. Airmodus was itself, co-founded in 2010 by the sub-micron particulate luminary, Professor Markku Kulmala who heads up the Division of Atmospheric Sciences at the University of Helsinki.

And over the last decade, we have learned far more about the massive negative health impacts associated with ultrafine (<100 nm) particles as well as the sources and significance of sub-5 nm particles and the creation, behaviour and fate of freshly nucleated aerosols.

The traditional instrument of choice for counting ultrafine particles has been the condensation particulate counter, or CPC. Whilst Airmodus offer a choice of two of CPCs (models A20 and A23) with compelling advantages over other brands, it is the A11 Nano Condensation Nucleus Counter system (A11 nCNC) and the A10 particle size magnifier (PSM) which Enviro Technology considers to be the most exciting and revolutionary products, opening up doors that were previously closed in the weird and wonderful sub-5 nm measurement realm. The A11 nCNC detects particles as small as 1 nm in diameter in real-time and also, importantly, the electrically neutral particles. In addition, the A11 cCNC operates in three modes: fixed, stepping or scanning and comes with comprehensive, yet user-friendly software to control the PSM and CPC, calculate particle concentration, calculate activation spectra and display and save data.

ET’s Duncan Mounsor concludes: “the small team of highly focused, highly specialised particle scientists at Airmodus are without doubt some of the greatest minds working on R&D and instrument development in this rapidly advancing area of atmospheric and environmental research. Having the Airmodus CPCs and the amazing A11 nCNC in our product range continues with our overall philosophy of introducing new technology to the UK market to enable scientists and researchers to continue to push the envelope and to do what has not been possible before”.

ET Introduces perhaps the World’s most innovative NOx analyser of the last 40 years.

Leading air quality monitoring equipment supplier, Enviro Technology Services Ltd (ET), is delighted to announce the launch of a revolutionary new non-chemiluminescent NOx analyser from analyser giant, Teledyne-API.

The new Model N500 CAPS NOx analyser uses superior Cavity Attenuated Phase Shift (CAPS) Spectroscopy to measure ‘true’ NO2, NOx and NO gases. CAPS technology is inherently accurate and sensitive, uses very little power and requires far less maintenance than chemiluminescence. The Model N500 raises the bar for NO2, NOx and NO measurement accuracy while simultaneously reducing instrument operation and maintenance costs.

ET’s Managing Director, Duncan Mounsor explains; “Teledyne-API’s first direct true NO2 analyser, the T500U has been a popular instrument for ET, particularly favoured by scientists and air quality specialists looking for a faster and more precise measurement of NO2 that cannot be offered by chemiluminescence. The new Model N500 like the T500U, uses CAPS technology for true NO2 measurement but now adds on this by measuring also the NO component of NOx. This really is a revolutionary instrument and we are very excited to be able to start offering it to our clients”.

Like all Teledyne-API gas analysers, the new Model N500 CAPS NOx / NO2 / NO analyser is available exclusively in the UK and Ireland through Enviro Technology Services Ltd.

Introducing the New ET SmogBox: MCERTS certified NO2 monitoring on-the-move!

What every air quality monitoring officer requires: A battery-powered, portable, MCERTS approved NO2 monitoring station for measurements on-the-move or for short durations in fixed locations.

Now you really can take high-quality NO2 measurements at air pollution hot-spots without having to worry about site power or planning permission. Just wheel the SmogBox along, taking measurements as you go, and when you get there, you can simply secure the unit to something suitable and leave it running, from either its own battery pack or connect up to mains (if available). Simple! 

Furthermore, an optional GPS-enabled web-logger means that you can easily track NO2 concentrations with your positioning, with colleagues being able to log-in in real-time and see exactly what the concentrations are at the exact location of the SmogBox.

ET’s Mike Webley says, “I recently took our SmogBox to London on the train and underground and made measurements along the way including walking through the City of London”. Mike continues “the SmogBox will run for around 6-hours on the standard battery pack it is supplied with and it weighs no more than my wife’s suitcase when we go on holiday!”.

Mike concludes “ET has often been asked by customers for Defra approved, portable AQ systems that can measure NO2 accurately, precisely and to a standard that can stand-up to data scrutiny and we think our new SmogBox ticks all of these boxes”.

For more information on the SmogBox or any of our other mobile monitoring solutions please contact ET on 01453 733200  sales@et.co.uk   www.et.co.uk

New BSI ISO 9001:2015 Certification for Enviro Technology

Stroud based air quality monitoring equipment and service provider, Enviro Technology Services Ltd, have recently made the successful transition from ISO9001:2008 to the latest version of the standard, ISO9001:2015.

The scope of ET’s BSI accredited ISO9001 Quality Management System covers “the design, manufacture, installation and servicing of environmental monitoring systems and associated equipment” and the certificate is valid until September 2018.

ET’s Managing Director, Duncan Mounsor explains “we have held our ISO 9001 quality certification for almost 20 years so having this certification is nothing new for us, but that said, we are pleased that the hard work that we put in for the transition to the new 2015 revision to the standard has paid off as there are only a few companies to have made the transition so far, and even fewer (if any) in the environmental monitoring sector”.

ET also operates BSI accredited and certified ISO 14001 environmental and OHSAS 18001 health and safety management systems.

Mounsor continues “quality is fundamentally important at ET; quality of products, quality of service and at every level within the business. And operating in the environmental sector it is essential for us to walk-the-walk and not just pay lip-service with regards to our environmental impacts and we are proud of our environmental achievements to date. These include changing our entire fleet of diesel estate cars to petrol-electric hybrids as well as a programme of changing all the fluorescent tubes in our head office over to LED panels which we are midway through.

Mounsor concludes “customers and stakeholders increasingly expect businesses to work to high quality, documented and externally audited management systems for quality, environment and health & safety. At ET, our accreditation and certification for all three of our systems is with BSI, one of the world leading, top-tier certification bodies who we are proud to align ourselves with. Having these systems requires top management commitment, investment and hard work and they are audited each year by BSI at their surveillance visits. We could have made the decision to go down the cheaper, easier, non-accredited self-audit road with our management systems, but feel that our customers, stakeholders and employees deserve more. It is all about continuous improvement at ET and that is what drives us forward.

New remote sensing LIDAR technology helps ET aim for the sky!

When it comes to air pollution measurement, ET has been leading the way, bringing innovative and cutting-edge instrumentation to market since its inception in 1983.

ET has always been an advocate of remote-sensing, for instance, using short or long-path optical technology to quantify gas concentrations over distances ranging from a few metres (for vehicle emissions monitoring) through to several hundreds of metres for urban, fence-line and fugitive emissions monitoring.

Examples include the Accuscan RSD vehicle emissions monitoring system that measures the individual exhaust emissions of each and every vehicle that drives through the cross-road optical path and the Opsis DOAS system that enables multi-gas measurements from single or multiple open paths in ambient air.

Most recently, ET has formed an exclusive partnership with Micro Pulse LiDAR from the USA and has been busy trialling the amazing mini-MPL system which stands for micro-pulse LIDAR. Micro Pulse LiDAR know a thing or two about remote sensing as the MPL was originally developed by NASA and instead of remote sensing looking down (i.e. from a satellite), the MPL, and now the mini-MPL, is ground based, looking upwards.

Designed to be housed in a small, temperature controlled weatherproof enclosure, the mini-MPL has a maximum vertical range of up to 15 km. That is about 9 miles for those who prefer non-metric units. It is therefore able probe up to the highest extents of the troposphere and beyond and with a minimum accumulation time of 1 second, builds up a detailed and dynamic profile of the atmosphere providing data on planetary boundary layer (PBL), cloud types (heights and tops) rain, ice-crystals and aerosol i.e. volcanic ash, Saharan dust as well as anthropogenic particulate matter etc.

The mini-MPL is amazing in many ways. Firstly, it is very small (hence the mini bit). It stands just less than 0.5 m high and weighs just 13 kg. Second, power consumption is very low at just 100 W. Third, it is classified as eye-safe. Fourth, it is a fraction of the cost of the large, power hungry LIDAR’s of days gone by and fifth, it is remarkably easy to use. Non-LIDAR specialists can be up-and-running with it in minutes and the Micro Pulse LiDAR analysis software makes simple work of understanding and presenting the wealth of information coming back from the 532 nm green eye-safe laser.

During 2017, ET will be demonstrating and trialling the mini-MPL at several leading Universities and working with some of the country’s leading LIDAR specialist and atmospheric scientists in order to showcase the huge capabilities and range of applications for this novel technology. Applications include; early warning of volcanic ash for airports, dynamic PBL monitoring, atmospheric aerosol research, weather forecasting and meteorology and even source apportionment of industrially generated particulate.

NEW T200P Photolytic NO2/NO/NOx Analyser

ET are pleased to introduce the NEW T200P Photolytic NO2/NO/NOx Analyser with patented high efficiency Blue Light Converter (BLC), also known as a photolytic converter.

The T200P is based on the standard T200 analyser but uses a photolytic LED array BLC converter to convert NO2 to NO rather than a traditional catalytic (stainless steel) or chemical reagent (molybdenum) based converter.

This may sound a bit complicated, but what does it mean in practice?

Being far more “specific” (and therefore with less measurement uncertainty) means that NO2 measurements are made more accurately and precisely than from regular chemiluminescent NOx analysers which are known to overestimate NO2 by up over 50% in some applications.

And as the T200P also measures NO, then users have the best of both worlds, precise and accurate NO measurements with enhanced NO2 measurement performance.

Perfect for roadside and urban background sites, especially those that are close to, or exceed the annual NO2 limit value of 40 µg/m3.

And if “true” direct NO2 measurement is what you are looking for, and don’t necessarily need the NO channel, then check out our most advanced NO2 analyser, the MCERTS approved T500U CAPS analyser.

For more information on the T200P (or any other of our NO2 and NOx analysers) call ET on 01453 733200 to speak to one of our specialists or download our handy NOx analyser comparison brochure at www.et.co.uk

The T500U CAPS NO2 Analyser - Now with added MCERTS

In 2015 ET announced the availability of the latest technology in ambient and trace level NO2 measurement with the T500U CAPS (Cavity Attenuated Phase Shift) direct reading NO2 Analyser, capable of “true” NO2 measurements across the ranges 0-5ppb through to 1 ppm.

We are now very pleased to report that the T500 has acquired MCERTS certification.

Now, along with our standard NOx monitor the T200 and the Ulra-sensitive T200UP (with photolytic converter) ET can offer an alternative to Chemiluminescence for those requiring MCERTS certification.

Representing the next generation of criteria pollutant monitoring technology for the direct measurement of Nitrogen Dioxide in air, the T500U CAPS measurement approach vastly reduces the amount of maintenance required whilst directly measuring NO2. Other benefits include, fast response, exceptional measurement sensitivity and low power consumption (80 Watts).

The T500 joins the Opsis System 300 open-path system (also sold by Enviro Technology) as one of only two non-chemiluminescent NO2 analyser techniques to receive UK ambient MCERTS certification.

ET upgrades the AURN with BAM1020 PM analysers

In March 2016, Bureau Veritas - in its role as Central Management and Co-ordination Unit of the UK Automatic Urban and Rural Network - on behalf of DEFRA, purchased a number of BAM1020 PM analysers from Enviro Technology Services for both PM10 & PM2.5 to replace existing TEOM analysers on the AURN under the ET trade-in offer, providing good value for money.

Sales Director, Mike Webley said, ET has been offering equipment trade-in for a number of years to Local Authorities, & we were pleased to offer a similar contract to the national network.

We all love summer

 At Enviro Technology Services Plc we pride ourselves on supplying top end, quality products to a market that requires accurate data for research projects using traditional reference methods of measurement. However, we do of course recognise that there are other opportunities for more indicative, cost effective solutions needed for certain applications.

For example: We all love the summer but there are a few downs sides to the wonderful weather that we need to be aware of.

Have you ever considered the health impacts of Barbequing for instance? It’s yet another form of air pollution and if you live in an area already suffering the effects of heavy traffic, like London, then seemingly small acts like barbequing can contribute considerably, especially when done in concentration.

For comparison, a recent study in the states noted that a diesel-engine lorry would have to drive 10 miles to produce the same amount of pm2.5 particles as a single char grilled burger.  (Researchers at the University of California)

 

Barbecuing is banned in many London Parks now as a result of local residents complaining of health related issues attributed to large numbers of people barbecuing in parks nearby on warm days. Research has shown a huge increase in PM2.5 levels when this occurs.

Of course there are other contributing factors to increases in particle matter in the air, including waste transfer stations, build-up of traffic outside schools during drop off and pick up and construction dust from residential developments, the list goes on.

Enviro Technology is offering the perfect solution for those needing to measure PM2.5 , PM10 or TSP particles from such situations - 
The Neighborhood Monitor from Met One.

It’s a simple, affordable, wireless solution. The purchase price includes everything you need:

  • Hardware
  • Sim cards
  • 3 years web access

All you need to do is turn it on.
