Enviro Technology announces the availability of the new T series gas analysers

World class supplier and leading UK exporter specialising in air pollution monitoring systems Enviro Technology Services Plc is pleased to announce the availability of the latest gas analysers on the market from Teledyne-API.

The T-Series models (T100, T200, T300 and T400) monitor levels of SO₂, NOx, CO and O₃ respectively and feature amongst other things a large, multi-colour touch-screen display/GUI.

For the T200 NOx Analyser, which is expected to be a best-seller, the levels of each gas (NO, NO₂ and NOx) can be seen on the screen simultaneously.

Each model includes LAN/Ethernet local area network capability as standard and are fitted with two front panel mounted USB ports for use with data sticks, computer mouse or other USB devices.

For the first time, an 8 x channel analogue input module is available as an option which can be used for logging data from other sensors such as met sensors etc.

Duncan Mounsor from Enviro Technology said: “These latest gas analysers are the most versatile and capable on the market. Teledyne has built upon the success of their previous E-Series models and created a range that is more technologically advanced, easier to use and has greater flexibility.

We are confident that the T series will be a popular choice for companies or individuals who are looking for the latest air quality monitoring equipment.”

The T series analysers have fold down front and rear panels which create easy maintenance access and filters can be changed quickly without delay.

The analysers are being used for the Institute’s field campaigns, which look at the ¹³C isotope content of CO₂ which leaves the soil surface. By measuring  the ¹³C content researchers can tell more about where the CO₂ comes from, whether it is new carbon respired by plant rootsor older carbon associated with the turnover of soil organic matter – this distinction can have important implications for the global carbon cycle.

The use of these analysers has revolutionised the way the Institute has collected, stored and analysed data during these campaigns.  Dr Andy Midwood from the Macaulay Institute explains:
“During previous campaigns we collected literally hundreds of gas samples in small vials then shipped them back to Aberdeen for analysis. On more than one occasion there have been problems and we lost valuable information due to leakages or faults.

Now with the Picarro’s we analyse as we go. We can see how the data looks, make changes to our measurement criteria and generally make sure the experiments go as planned. This is only possible because the Picarro is so portable, in terms of size, power consumption and ease of operation.”

Duncan Mounsor from Enviro Technology said: “We are delighted that the Picarro analysers have been so well received by the Macaulay Institute.

In recent years we have expanded our range of quality specialist gaseous and particulate systems for scientific and research applications. We have noticed a need for more high tech, as well as portable equipment as it is often transported around the world.”

For further media information, please contact Rebecca Bushell at Trailblazer PR on 01453 887 777 or 07980 601870. Email rebecca.bushell@trailblazerpr.com.

The seminars will be held at Weetwood Hall, Leeds on 30^th of September and Celtic Manor, Newport on 14^th October.

Each seminar will be packed with ideas through practical sessions and case studies to guide attendees towards best practice for industrial air emissions.

Duncan Mounsor from Enviro Technology said: “The seminars are ideal for Process Operators who are responsible for specifying and maintaining equipment to control industrial air emissions and meeting site environmental obligations.

The content of the seminars will range from the selection, installation and maintenance of CEMS, to advice on choosing the right technology for particulate emission monitoring and an overview of ambient air quality monitoring for industry. The seminars are sure to be informative and insightful.”

Greywolf DirectSense IAQ Monitor

Enviro Technology Services Plc, which is a world class supplier and UK exporter specialising in environmental monitoring instrumentation for air quality monitoring and industrial emissions applications is adding to its services by offering indoor air quality monitoring.

The company is the sole UK distributor for the leading indoor air quality (IAQ) monitoring products DirectSense® from GrayWolf.

The DirectSense® monitors are state-of-the-art and allow the user to undertake IAQ surveys with ease and comfort. The monitors come in two parts, a probe and pocket PC. The probe is designed to be used for walk through surveys and or can be supplied with a tripod and left in-situ for longer term monitoring which will look at trends in IAQ.

The pocket PC generates the survey information at the touch of a button and can connect to a computer, laptop or notebook using XP/Vista/WIN7. However, the kit can also be supplied without the pocket PC, but with software suitable for use with a customer’s own laptop.

Jamie McNee, Sales Engineer at Enviro Technology, said: “We really believe that the technology from Graywolf is a lot more advanced than the current IAQ monitoring equipment that is available and we are looking forward to demonstrating it to more and more customers.

Although the UK has been carrying out IAQ monitoring in offices for many years other places such as schools, universities and public places seem to unaware that poor IAQ levels can have health implications despite these being well documented. We believe there is a great market for IAQ and know that DirectSense® delivers the right option for proactive IAQ management.”

The key features of the monitors are as follows:

• Simultaneous measurement of up to five (5) key IAQ indicators; VOCs, CO2 (dilution ventilation), CO, %RH, °C/°F in one probe
• Manual “snapshot” or automatic “trend” datalogging available
• Store enhanced survey information on-site; data and text, drawings, audio notes, photos etc

Opsis AQM System at Tower Bridge

Due to the well-proven evidence that correlates high PM levels with mortality rates, the answer is probably no, but NO_2, and more specifically “direct NO₂” seems to be a real hot potato at the moment.

If you have been to any of the recent high profile IAQM and EPUK conferences over the last few months, chances are you will have sat through one of the many “direct NO₂” presentations that are currently doing the rounds. These have been delivered by AQ luminaries such as Dr David Carslaw (ERG Kings College) and Dr James Tate (ITS Leeds University) to name but a few.

So what is all the fuss about?

Well, as we all know, it is widely accepted that NOx levels in urban areas have been falling steadily over the last 10 years. So along with drastic reductions in CO levels as well over the same period, this surely bodes well for local air quality management, right?

Well, not exactly.

Recent studies and data collected from several urban and kerbside AURN stations show, that although overall NOx levels are down, NO₂ levels are worryingly on the up at certain “hot-spots” across the UK.

Leading academics and consultants, now think they know why, and it would appear it is primarily down to “direct NO₂” tailpipe emissions.

Sadly, our love affair with the motor car is still as healthy as ever and incentives to kick-start some life into the struggling motor industry, like the UK’s highly successful “scrappage scheme” have in fact had a detrimental effect in our on-going battle to improve air quality in some areas. So too has been the “dieselisation” of the vehicle fleet over the last 10 years (i.e. PM₁₀).

Why is that then?

Well, the motor manufacturing industry is targeted, through the Euro engine classification system (i.e. Euro IV, Euro V and now Euro VI) to reducing amongst others, NOx, PM and CO₂ emissions for new vehicles. NO₂ has traditionally only been a very small part of the overall NOx emission, and clean engine technology has been refined, developed and rolled out now to ensure our overall NOx emissions are within the EU Euro specs. However, approximately 40% of vehicles sold these days are diesels and as we all know, diesel vehicles produce much higher levels of those “killer” PM₁₀ particles then petrol engine vehicles and so the motor manufacturers have had to come up with ways in keeping PM₁₀ levels in check too.

So how do they do that and what has it got to do with NO₂?

Well, we have all heard about catalytic converters and particulate traps etc. The latter mainly work by “burning” the particles before they come out of the tailpipe. It is a thermal oxidisation process.

When you burn air, the nitrogen compounds get converted to NO₂ and this, is the heart of the problem.

In a major drive to help reduce CO₂ emissions, diesel car uptake has never been so high. This is fuelled (no pun intended) by the HMRC CO₂ scale and Benefit in Kind taxation system for company car drivers. Essentially, you stand to pay far less tax if your company car is of the diesel type.

And it is not just cars, the London Low Emission Zone has forced taxi and HGV owners and operators to comply with new rules that have on one hand, ensured that our buses, HGV’s and taxi’s are cleaner (in terms of CO₂ and particulates) but they are all adding to the growing direct NO₂ problem.

So in a nutshell, in terms of NO₂ at least, recent studies have demonstrated that some of the new cars that have come into service during the scrappage scheme (over 400,000 vehicles), many emit far higher levels of NO₂ than the 10 years + old ones that they have replaced!

Sure, the NOx, PM10, HC emissions are demonstrably lower, but not necessarily NO₂.

This conundrum is causing a major headache for Defra and the Air Quality Helpdesk, who at this moment in time, do not know how to advise worried Local Authorities who ask, what can we do about this?

One thing that is for sure, is that it is very complicated and extremely difficult to model future NO₂ levels. I recently heard that one leading UK University ran a 27-dimensional model on its biggest, fastest super-computer and it took a few days to do some number crunching.

And then there are the model uncertainties. Getting a result that is within +/- 20% accuracy I’m told is very good indeed. And what do we validate the models with?

The answer to that is that we use diffusion tubes and Chemiluminescent NOx analysers.

But that is OK isn’t it?

Well that depends on your point of view…

VHS was OK before DVD came along, cathode ray TV’s were OK before Plasma/LED TV’s came along, the slide rule was probably OK before the pocket calculator came along (but I’m too young to remember those).

Chemiluminescent NOx analysers are OK, and to many, they are the “Gold Standard” for NOx monitoring, and diffusion tubes? Well that is a whole other debate.

Now the focus is squarely on NO₂, and chemiluminescent NOx analysers have one fundamental problem and that is they don’t actually measure NO₂ at all, instead they convert NO₂ back to NO using a high temperature molybdenum converter at approximately 315 ^OC. The sample gas is actually switched either through the moly converter or directly into the reaction cell thereby giving us the NOx – NO = NO₂ measurement equation.

In theory this is great, but it is dependent on certain assumptions and critical factors. The first of which is that moly converter is efficient. In a perfect world, this efficiency should be 100% but in practice it may be closer to 95% on a well maintained, modern NOx analyser and could be far less on older analysers or those that are not serviced frequently or maintained and calibrated adequately.

The second consideration is measurement uncertainty. Again, in an ideal world, every part of the analyser, calibration system and sampling system should be studied and all the “uncertainties” added up to give an overall expanded uncertainty which we should then use as a measure of quality assurance.

Thirdly moly converters can also convert other nitrogen compounds into NO, not just the NO₂. The catalytic technique is not 100% selective to NO₂ only, so any other oxides that are inadvertently converted to NO will be “calculated” as NO₂ even if they are not really.

Chemiluminescent NOx analysers, like all what we call “point” analysers are a hybrid pneumatic/electronic box of tricks that sample a relatively small volume of sample air (i.e. 800cc/min) using sample lines (of varying lengths and conditions), pumps (in various states of operational condition) and solenoid valves, flow restrictors, critical orifices, sample inlet filters, converters, catalysts, scrubbers and a myriad of other things.

All of these components have a bearing on measurement uncertainty and what comes in at the end of the sample tube, will never get to the detection part of the analyser 100% intact. There are losses, chemical reactions and interferences all along the way.

So how sure are you now that the 25 ug/m3 NO₂ that your NOx analyser is displaying really is 25?

OK, so what alternatives are there to the good old Chemiluminescent NOx box?

Surprisingly few is the answer to that, and even fewer that “really” work for low-level ambient air quality monitoring applications.

However where all this is leading us to is something called UV DOAS!

UV what??

UV DOAS, or to give it its full name Ultra-Violet Differential Optical Absorption Spectroscopy.

Firstly, UV-DOAS is a non-contact, non-pneumatic optical system that measures NO₂ “directly” and many other gases (such as O₃ SO₂ and BTEX) in real-time over for example a 500m open-path in ambient air.

Using three main components, an emitter, a receiver and a small, compact DOAS analyser (a computer controlled UV spectrometer) DOAS detects and measures target gases by analysing their unique spectral absorption characteristics (think of it as a sophisticated gas fingerprinting system).

Each gas has its own unique “fingerprint” and DOAS is able to look at the ones of interest and these only. It not only computes the gas concentration but also the standard deviation of each measurement, which is a major quality assurance improvement over “standard” analysers that pretty much expect you to “gauge” the overall quality after you have worked out all those measurement uncertainties touched on briefly above.

DOAS is fast, inherently accurate, requires no sampling system, the minimum of calibration (six-monthly is more than adequate) and more importantly is far more representative of local air quality levels than for instance, the data generated from a single NOx analyser, after all, it is monitoring a much larger sample (several hundered meters of air) as opposed to perhaps 800cc/min from a single inlet head.

It has also got the right credentials as it internationally approved and validated and in the UK has an MCERTS certificate for NO₂ SO₂ O₃ and Benzene.

Gas molecules are as we know, very small. The NO₂ molecules that we are trying to measure with our chemiluminescent NOx analysers when mixed up in ambient air are almost mind-bogglingly well dispersed and distributed. Just think about the nomenclature that we use, for instance “parts per billion”. Think about it, this means one NO₂ molecule in one billion parts of air.

Sure, if we find a few of the NO₂ molecules in ambient air, our chemiluminescent analysers are sensitive enough to measure them (after being converted back to NO first of course) but what if those molecules evade capture through our relatively puny 800 cc/min sample lines?

Well they won’t get measured.

Molecules will, and do, do their own thing. They are here one second, somewhere else the next, (the realm of the quantum) and if they are 1,5,10 or 100m from your NOx analyser sample inlet, the fact is, they won’t get measured. To get measured, they need to be pretty much floating about right by your sample inlet system, and then they might even slip away if the wind changes!

But imagine a beam of light running alongside the busy road we want to take our NOx measurements from, let’s say 300m long for arguments sake. We know the NO₂ levels are high in this area from our modelling or diffusion tubes surveys. Just think of all those NO₂ molecules that will be potentially present in that 300m section of horizontal air mass we are shining our light through. Chances are we are going to do a far better job of finding them and measuring them in a far more representative manner than from our single chemiluminescent NOx analyser.

Chances are however, that the real concentrations might actually be higher (or lower) than we expect as we now have a system that is far more adept and representative than before.

However, to coin another well used phrase “to measure is to really know” and now that the UK is facing all manner of well reported problems with cities such as London reported by some quarters to be the most polluted city in Europe, isn’t it time that we took a fresh look at alternative monitoring technologies?

After all, who still uses VHS, Cathode Ray TV’s and slide rules..

Accessible Air Quality Info Should be a Right Not a Privilege

When we turn on the tap, we know that the water coming out will be of a consistently high quality, and we can choose, if we so wish, to drink bottled water instead, should we have any doubts.

This is not so with the air that we breathe. Unlike the water that we drink, we have no guarantee – and in many cases no information – telling us that the air quality in our towns, cities and even rural areas is of an acceptable and safe quality.

Recent headline grabbing stories about the number of UK deaths hastened by air pollution is therefore invariably going to come as a shock to many people who will have until now not fully understood just how dangerous modern air pollution really is.

That said, the recent headlines risk oversimplifying the issue of air pollution. They also overlook the many complex factors that influence air quality, and the vast improvements that have been made over the last 20 years, according to air quality monitoring specialist Enviro Technology Services plc.

“It has long been known that air pollution has a serious impact on health, and that it can hasten death,” says Duncan Mounsor, Sales and Marketing Director at Enviro Technology. “Proactive steps have been taken at a local, national and international level to address the problem, and in general UK air quality is far better now than it was 20 or 30 years ago.

“The trouble is, air quality information is not always made available to the public as regularly, consistently or prominently as it perhaps should be. And the latest figures relating to air pollution deaths in the UK may well drive forward the message that we need to know far more about the quality of the air that we all breathe.

“Yes, you can dig about on the internet and find some information about current air quality levels but you have to know where to look. My feeling is that air quality levels should be presented in a far more proactive and highly visible way on the television and on the radio, just like the weather forecast. We have started to see things like the UV Index on the weather forecast, why not air quality forecasts?”

Regarding the air pollutants themselves, Mounsor accepts that whilst some pollutants have been dramatically reduced, others appear to be on the increase. This has led to the development of sophisticated monitoring equipment that can detect individual pollutants at very low levels and – in the case of vehicle emissions (one of the largest contributors to poor air quality) – systems that can categorise the contribution of various pollutants from specific vehicle types and ages.

Enviro Technology supplies air quality monitoring systems to central Government and local authorities to enable them to continuously monitor levels of air pollution. It can also provide software, public information systems and websites to help rationalise the data, and make it publicly available via high impact websites such as www.airqualitydata.com.

“It does no harm to remind people of the importance of air quality,” concludes Mounsor. “However, it needs to be kept in perspective and addressed intelligently rather than used to frighten people. The UK Government has one of the largest, most modern, well-equipped and well-maintained air quality monitoring networks in the world. This plays a vital role in improving the situation now and in the future – once you measure air quality effectively, you are better able to manage it.”

State-of-the-art Mobile Air Quality Monitoring Vehicle supplied by ET

ET devises mobile monitoring units for Air Quality Cell

The Environment Agency-chaired Air Quality Cell, set up to provide a multi-agency response to major air quality incidents, is using sophisticated mobile units from Enviro Technology as a core strategy component.

Enviro Technology was selected for the multi-million pound project after a competitive pitch involving a complex brief. The air quality monitoring specialist is providing two bespoke, well-equipped vehicles that use groundbreaking technologies and meet stringent requirements, such as weight and power restrictions.

“In the event of a major incident the Air Quality Cell will be convened, and rapid response measures including vehicle deployment, are implemented,” explains Gillian Hickey from the Environment Agency. “The mobile stations need to be in situ, gathering data and samples for analysis, within hours of the initial alert.

We chose to work with Enviro Technology as the team’s response to our challenging brief demonstrated intelligence and innovation.”

Enviro Technology has also secured a three year service and maintenance contract for the mobile monitoring stations. A dedicated engineer has been recruited to accompany the vehicles, provide onsite technical support and ensure all equipment is functioning at its optimum level for the duration of an incident.

It is anticipated that the Air Quality Cell will be fully functional, with monitoring and improved modelling capabilities for England and Wales, in April 2010. As part of interim arrangements, the mobile units have been used in response to several incidents, including a fire at a tyre recycling plant

Pollutants that can be detected and measured by equipment on the mobile stations include SO2, Nox, NH3, CO, PM10 and PM2.5. The vehicles also carry their own generators and are fitted with pneumatic stabilisers. In addition, a 360° weather-proof webcam and net mast enable Agency staff to keep in touch with remote colleagues and share real-time incident information.

“This is probably the most exacting brief we have ever had to work with,” says Duncan Mounsor, Sales & Marketing Director at Enviro Technology. “But the result is a pair of truly state-of-the-art mobile air quality monitoring stations.”

Notes to editors

About the Air Quality Cell

The Air Quality Cell is an initiative to provide coordinated data monitoring and modelling in the event of a major air pollution incident in England or Wales. When an incident occurs, the Environment Agency, in consultation with the Health Protection Agency (Chemical Hazards and Poisons Division) will initiate a response in collaboration with the Met Office, Health & Safety Laboratory and Food Standards Agency.

The Air Quality Cell will convene in the following scenarios:

• Major air pollution incidents which affect England or Wales.
• Deliberate or hostile acts, not involving chemical warfare agents (e.g. explosion at a chemical plant).
• Emergency phase of an incident – at the end of this phase the Cell will withdraw and coordination of any ongoing environmental modelling and monitoring will be handed over to the Recovery Co-ordination Group (or similar) in recovery phase.

CEMS Sales Surge for Enviro Technology in 2009

GDF Suez Energy UK has awarded air quality monitoring specialists, Enviro Technology, a contract to supply five Continuous Emissions Monitoring Systems (CEMS) for its Teesside based Combined Cycle Gas Turbine (CCGT) power station.

With a generation capacity of 1875 MW, the power station is Europe’s largest CCGT plant. It produces enough power for approximately 3% of the UK’s needs.

Enviro Technology have supplied five OPSIS systems to measure Nitrogen Oxide (as NO and NO₂), Sulphur Dioxide (SO₂), Carbon Monoxide (CO) and Oxygen (O₂). Associated reporting and data logging software and products have also been purchased.

Says Enviro Technology’s CEMS Engineering Manager Phil Battye: “We are extremely pleased that, following a competitive selection process lasting an average of three years, we have been awarded this contract.

GDF Suez UK has been impressed not only with the calibre of equipment and service we offer, but our honesty in terms of ongoing operations costs. These factors, plus our proven track record of high quality on-site service, have helped us to secure these contracts.

Says GDF SUEZ Energy UK’s Electrical, Control and Instrumentation Engineer Patrick Pisani: “There are three key reasons we awarded Enviro Technology this contract. Firstly, we were impressed with the tailor-made MCERTS-approved system they provided for us based upon their knowledge of our industry. Secondly, their honesty in terms of pricing. And last but not least the superior after-sales/ongoing maintenance service they offered.

“This contract award has been three years in the making and, at every step of the way, ET’s CEMS team have gone out of their way to supply us with the information we needed in order to make well-informed, commercial decisions.

Nitric Oxide Limiting Factor Dissapears Following Opsis Upgrade

Air quality monitoring experts, Enviro Technology, have announced important upgrades to their OPSIS DOAS system for continuous emissions monitoring (CEM).

Due to customer demand, OPSIS have increased the length of their fibre optic cable for Nitric Oxide (NO) measurement. Whereas previously NO could only be measured up to 10 metres, due to this upgrade it can now measure this compound up to 25 metres.

Enviro Technology’s sales and marketing director Duncan Mounsor said: “Previously the measurement of NO has been the limiting factor for those companies looking to monitor continuous emissions.

“Before this upgrade, and due to the short NO cable length, continuous emissions monitoring cabinets would have had to be placed, in some cases, half way up the stack. But now, due to the longer cable length, cabinets can be stored at ground level which in terms of ease of installation, cost and health and safety concerns, is good news for the customer.”

The air quality monitoring specialist’s Sales and Marketing Director, Duncan Mounsor, spoke to a wide range of delegates during the course of the two-day event. He particularly noticed the mindset of energy providers and waste incineration businesses starting to change as they appreciate the benefits of a long-term approach to monitoring.

“People are realising that ‘cheap and cheerful’ solutions simply don’t meet the required standards over time,” says Mounsor. “It’s important to install high quality equipment, set contractual service level agreements and go through quality assurance schemes. Otherwise, it’s too easy to fall foul of the Environment Agency. You need to be able to rely on your equipment, and to be confident that if it does let you down, someone will be there to fix or replace it quickly.”

Enviro Technology’s conference theme was ‘take it easy’, demonstrating that better quality products enable businesses to relax in the knowledge that their emissions monitoring is under control.

The supplier ran four workshops, including one looking at fenceline monitoring where delegates were able to see its mobile OPSIS air quality monitoring system in action. The system monitored air quality live outside the Bretby Conference centre.

“Attendees were interested in the OPSIS system, and were full of questions surrounding issues such as path lengths and site locations,” continued Duncan.

Workshop topics were chosen following discussions with industry professionals about the subjects and issues that are most pertinent to them. For instance, the CO2 capture session tapped in to current concerns surrounding the commissioning of new power stations in the UK.
