DustScanAQ installs, operates and manages a range of air quality monitoring equipment, and provides project specific data management solutions. We have experience with big data analysis in its management, quality control, interpretation, data visualisation and reporting with a range of simple desktop based solutions to high level cloud based data driven technologies. Through continuous environmental monitoring, we also assist clients in developing bespoke data driven environmental management and alert systems to improve site compliance.
The equipment we use ranges from simple passive diffusion tube sampling through short term pumped sampling to sophisticated, automatic air quality stations for continuous air quality monitoring. Our low -cost passive diffusion tube and thermal desorption sorbent tubes monitoring services range from:
- Acid gas diffusion tubes - Hydrogen fluoride (HF), Hydrogen chloride (HC), Nitric acid (HNO3), Hydrogen bromide (HBr), Phosphoric acid (HPO4) and Sulphuric acid (H2SO4);
- Ammonia (NH3), Formaldehyde (CH2O), Hydrogen Sulphide (H2S) diffusion tubes;
- Anaesthetic Gas Monitoring (Nitrous Oxide (N2O);
- NO2 and Nitrogen Oxides Diffusion Tubes;
- Ozone Diffusion Tubes
- Sulphur Dioxide Diffusion Tubes; and
- Volatile Organic Compound (VOC) and Polyaromatic hydrocarbons (PAHs) sorbent tubes.
We also manufacture and supply an indicative air quality monitoring system: the DS500X filter-reference PM10 or PM2.5 sampler that also incorporates air pressure, temperature and humidity sensors. For more information about this system please refer to the DS500X page. Where real-time air quality monitoring data are required (indicative or reference), the most suitable continuous air quality monitoring equipment is identified for specific site requirements (this may sometimes differ from what has been specified in planning or contract conditions). Continuous air quality monitoring stations infer pollutant concentrations (such as PM10, PM2.5, NO2, CO, SO2, O3, heavy metals and PAHs) in real-time, typically using light-scatter, electrochemical sensors and gas analysers. Whilst questions remain over the accuracy of low-cost indicative air quality monitoring sensors, they can be used to alert site operators or regulators to short-term peaks in pollutant concentrations so that immediate control measures can be implemented or specific works suspended.
For short-term environmental monitoring studies and surveys we typically use hand-held, real-time particulate (such as the Quest EVM) and gas (such as the ToxiRAE) samplers. For longer term site monitoring we maintain a number of continuous monitoring instruments (ranging from indicative Turnkey Osiris to Thermo Fisher TEOM FDMS or Partisol particulate matter reference instruments) that are typically hired by clients for whom we report and manage the air quality monitoring data produced.
