Gas Analysers 2025

Descriptions

The UK Automatic Urban and Rural Network (AURN) is the Environment Agency’s compliance network for the reporting of pollutant concentrations the Air Quality Directive (AQD) 2008/50/EC. This was transposed by respective Air Quality Standard Regulations across the UK and the Devolved Administrations. The network provides measurements of a range of pollutants including Particulate size fractions (PM10 and PM2.5) and the following gases: oxides of nitrogen (NOX), nitrogen dioxide (NO2), ozone (O3), sulphur dioxide (SO2) and carbon monoxide (CO). Further details of the current network are available on http://uk-air.defra.gov.uk/. The Environment Agency on behalf of the Department for Environment, Food and Rural Affairs (Defra), Affiliated Local Authorities and Devolved Administrations is seeking to procure gas analysers to measure the following gases: oxides of nitrogen (NOX), nitrogen dioxide (NO2), ozone (O3) and sulphur dioxide (SO2).

Engagement

F01:PIN https://www.find-tender.service.gov.uk/Notice/019939-2024 II.1.4) Short description The Environment Agency requires the supply and installation of the following air quality monitoring instruments: • NOx and NO2 analyser which is compliant or equivalent with “BS EN 14211:2012 Ambient Air Quality” which uses the standard method for the measurement of the concentration of nitrogen dioxide and nitrogen monoxide by Chemiluminescent. • SO2 analyser which is compliant or equivalent with “BS EN 14212:2012 Ambient Air Quality” which uses the standard method for the measurement of the concentration of sulphur dioxide by ultra-violet fluorescence.  • Ozone analyser which is compliant or equivalent with “BS EN 14625:2012 Ambient Air Quality” which uses the standard method for the measurement of the concentration of ozone by ultraviolet photometry.  Approximately 23 NOx, 2 SO2 and 30 O3 analysers will be required before 31st March 2025. If you have an interest in this requirement please get in touch with the procurement team, no later than close on Friday 12th July 2024, at: DGC-LAWW-buyer@defra.gov.uk The team are interested in gaining some information from the market, so any interested party will receive a questionnaire by email with some commercial and technical questions. This will be sent w/c 15th July 2024.
