Metir and Swansea University advance field-ready PFAS detection technology

 

Successful feasibility of 'Lab in a Van' solution positions Metir at the
forefront of sustainable PFAS monitoring amid rising regulatory focus

 

Metir plc (AIM: MET), a global leader in mobile and point-of-use water and
environmental testing, announces progress in its collaboration with Swansea
University to develop next-generation methods for detecting PFAS 'forever
chemicals'.

 

Continuing media and regulatory attention have underscored the urgent need for
more effective monitoring tools, as new evidence reveals widespread PFAS
contamination in water and soil, carrying significant risks to human health.
With authorities reviewing potential limits and clean-up mandates, the ability
to detect PFAS quickly and sustainably in the field has never been more
important. In parallel, Metir is engaging with relevant UK authorities and
industry bodies on its unique technology.

 

Research led by Dr Ruth Godfrey at Swansea University has demonstrated the
feasibility of integrating portable liquid chromatography-mass spectrometry
(LCMS) with innovative low-waste extraction materials, enabling the creation
of a compact 'Lab in a Van' system. This field-deployable platform enables
rapid and accurate detection of PFAS in water, soil, effluent, and biological
samples on-site, significantly reducing analysis turnaround time and
environmental impact compared to traditional laboratory methods. PFAS levels
of health concern are so low (parts per trillion) that testing conventional
grab samples is a suboptimal method because collection, transportation to, and
delays at the laboratory can easily result in corrupted samples with
inaccurate results.

 

It is almost certain that forms of PFAS chemicals will continue to be
manufactured into the future as non-replaceable production processes for many
essential applications. The waste streams of these industries will be closely
controlled and monitored. Very accurate PFAS detection and measurement
technologies that Metir can supply will be able to fulfil this need.

 

Metir supported the programme through a three-and-a-half-year PhD sponsorship
that confirmed its proprietary mass spectrometry platform can identify a
broader range of PFAS compounds with exceptional accuracy and sensitivity.
Successful field trials on a Welsh river in April 2025 validated the
technology's real-world capability. Metir continues to collaborate with
its large US-based distribution and instrumentation partner to optimise and
scale the detector for potential commercial deployment, particularly in the US
market. A recent visit to the partner's facilities in the US confirms the
progress being made.

 

By combining Swansea University's academic excellence with Metir's expertise
in sustainable mobile testing solutions, the partnership is advancing a vital
tool for addressing one of the world's most persistent environmental
challenges. These innovations will help regulators, utilities, and industries
meet increasingly stringent environmental standards and enhance public health
protection against PFAS exposure.

 

Bob Moore, Executive Chairman and Chief Executive Officer of Metir plc, said:

"PFAS contamination is one of today's most pressing environmental and health
challenges. Our partnership with Swansea University and collaboration with our
US partner accelerates the development of practical, scalable detection
technologies while creating a strong commercial opportunity for Metir. This is
a clear example of our strategy to turn cutting-edge science into field-ready
solutions."

 

Dr Ruth Godfrey, Associate Professor in LCMS at Swansea University, added:

"Our research focuses on translating laboratory excellence into practical
technologies. Partnering with Metir allows us to create deployable systems
that address urgent monitoring needs and provide a sustainable route to
tackling the PFAS problem at scale."
