22 Air Monitoring
Free to attend air quality and emissions monitoring exhibition and conference
Does your company have a need or a responsibility to monitor or measure air quality or emissions or comply with environmental regulations and targets? If so, you will want to attend AQE 2024! Registration is now open for AQE, an exhibition and conference on air quality and emissions monitoring, taking place at the NEC in Birmingham, UK on the 9th & 10th October. Your free entry pass will give you the chance to meet, network, compare prices and solutions, and discuss your latest projects with leading manufacturers and suppliers of air monitoring solutions and services. This year’s AQE will be the biggest AQE event to date and the most important air quality and emissions meeting since 2022. There will be over 100 exhibitors displaying the world’s leading air monitoring technology. The exhibitors will all provide expert advice on how to fulfi l your specifi c applications and answer any technical questions you may have.
Alongside the exhibition, AQE 2024 boasts an excellent line up of headline speakers and industry leaders presenting on a variety of topics, including air quality, air quality networks, emissions monitoring, CCUS, odour monitoring, fi ne particulate monitoring, gas analysis, manual stack sampling, fugitive emissions, indoor air quality, fence line monitoring, methane monitoring, data acquisition, hydrogen testing and measurement, big data, AI and machine learning, gas detection and more.
AQE will be of value to process operators, local authorities, environmental managers, instrument users, technicians and regulators. Finally, as a bonus to your registration for AQE, visitors will also gain entry to WWEM, our water and wastewater monitoring event, which is co-located with AQE. Head to
www.ilmexhibitions/aqeshow/registration to register today.
We look forward to seeing you in October! For More Info, email:

analysis just became a whole lot easier Mercury is a specifi c element; in its elemental form (HG0) mercury is relatively easy to handle and measure. However, in chemical and combustion processes, mercury will be oxidized to some degree, to be measured, these forms of mercury (HG+, HG++) need to be reduced to elemental mercury in a converter process. The fi rst accepted method for performing such reductions was based on wet chemistry, it is still perceived to be the standard method, but this procedure can only be carried out in a lab. Another method involves the use of an extremely high-temperature oven, which breaks down the chemical bonds thus enabling mercury to be analysed, but, whilst this can take the process away from the lab, it is not without problems of its own, in terms of reliability.
The OPSIS System400Hg provides an alternative approach, which compares very favourably with the alternatives. The reduction is carried out in a temperature-controlled canister using a material that reduces the oxidised forms to elemental mercury at a relatively low-temperature range of 235-250 °C. This is a solution that is reliable and durable, and it works reliably for unattended, extended periods with no measurement drift. The OPSIS System400Hg extracts a sample gas fl ow through a heated probe with a dust fi lter. The fl ow rate is a few litres per minute. The fl ow goes through a heated sample line and then through the reduction converter. Gas containing elemental mercury is then ready to be measured in the temperature-controlled stainless-steel cell, with quartz glass windows.
The OPSIS UV-DOAS is a well-established technology for type-approved, certifi ed measurements of a wide variety of gases, including elemental mercury. The system includes a source emitter with a Xenon lamp that produces a well-collimated beam of white, full- spectrum, light. On the other side of the measurement cell, there is a receiver that collects the light and sends the signal through a fi bre optic cable to the UV-DOAS spectrometer. The analyser digitises and collects hundreds of samples per second and its integrated computer calculates the results and communicates the information to external data collection systems.
The OPSIS UV-DOAS is a non-intrusive type of gas analysis system that has no direct contact with the process gas; the measurement is made optically. This leads to signifi cantly improved reliability and durability when compared to conventional technologies.
The already TUV-certifi ed OPSIS System400Hg combines the features of UV-DOAS technology with the most recent advances in mercury reduction technology. With ever more stringent global legislation for mercury emission, this state-of-the-art analyser takes the stress away when reliable and precise measurements are needed for environmental compliance and protecting communities.
