Automatic Particulate Matter Analyser Contract for Ambient Air

The EA Air Quality contracts team have been given project approval to procure analysers that can measure Particulate Matter (PM) 2.5 analysers as part of the establishment of a 99 site expansion at near source and urban background locations.

The establishment of the sites will be phased over the financial years 22/23 and 23/24 and the instrumentation will need to be ready for installation as the new sites are established. Once operational the instruments will be part of the AURN network but will be managed and delivered under a new contract being procured during 2023.

This expansion is a specific requirement requested by Defra for more PM2.5 Particulate Matter (PM) instruments to get more measurement evidence base for the PM2.5 environmental targets. The targets are a Statutory Instrument being set under the Environment Act 2021, to be put before parliament by 31st October 2022.
