Puraffinity, a UK-based water technology company specialising in advanced materials for removing per- and polyfluoroalkyl substances (PFAS) from water, has entered into a collaboration agreement with Metir to evaluate Metir’s proprietary PFAS detection platform alongside Puraffinity’s PFAS removal technology in field applications, as announced by Metir on 23 Sep 2026.
Under the agreement, Metir and Puraffinity will evaluate Metir’s PFAS detection platform, which uses Microsaic Systems’ technology, alongside Puraffinity’s PFAS removal technology to provide rapid analytical data at the point of treatment.
The programme, focused on the semiconductor manufacturing industry, will measure PFAS concentrations in water before and after Puraffinity treatment. This will provide near real-time data on treatment performance and PFAS removal, while assessing the potential for an integrated “detect, treat and verify” approach.
PFAS analysis typically requires samples to be collected and transported to specialist laboratories for testing using conventional mass spectrometry equipment, which can result in delays before results are available. This can limit real-time process optimisation and make it more difficult to anticipate PFAS breakthrough. Metir’s proprietary miniaturised mass spectrometry platform has been developed and is being optimised to provide sensitive PFAS detection in a smaller, lower-energy and field-deployable format.
Puraffinity’s small-footprint adsorbent media technology is designed for applications including municipal and industrial water treatment, landfill leachate, contaminated groundwater and environmental remediation. Its compact footprint, ease of servicing and high efficiency are intended to minimise disruption to core site operations while supporting stringent compliance requirements in the semiconductor industry.
“The ability to combine PFAS detection with treatment and rapid on-site verification could provide a compelling proposition for the growing global PFAS remediation and water treatment markets,” said Bob Moore, executive chairman and chief executive officer of Metir.
“PFAS treatment is judged by what leaves the vessel,” said Vincent Caillaud, chief executive officer at Puraffinity. “Measuring it on site, in near real time, lets operators act on current data instead of waiting for the laboratory. Just as importantly, it enables real-time optimisation of our deployed solutions.”
