Ian added that progress will also depend on better toxicology data.


“We can’t just measure everything,” he says.


“All PFASs exhibit extreme persistence, which includes those that naturally transform into persistent daughter products, but we need to prioritise PFASs based on bulk and dispersive usess, bioccumulation potential, mobility, toxicity and exposure.


“That’s where collaboration between chemists, toxicologists and regulators is essential.”


Collaboration and transparency


Ultimately, PFASs monitoring requires not just better tools, but also better communication. As Ian concluded: “There’s no silver bullet.


“It’s about combining targeted, total and non-targeted methods where they make sense, being honest about limitations, and ensuring stakeholders - from regulators to communities - understand what the data means.”


Nick agreed: “This is an area where collaboration matters.


“No single lab, company or regulator can solve PFASs monitoring alone.


“Sharing methods, sharing data and building confi dence in the results is the way forward.”

New probe recalibration and reuse service


Vaisala has launched an innovative new instrumentation service, ‘Vaisala Circular’. Developed for applications where measurement accuracy and uptime are critically important, Vaisala Circular is a comprehensive service platform designed to ensure that measurements are as accurate, uninterrupted and reliable as possible, in the long-term.


Under Vaisala Circular, customers have a dedicated pool of measurement probes, securely stored and maintained at Vaisala’s service centres. When calibration is necessary, customers simply order replacement probes from Vaisala online and swap them in - thereby minimising measurement downtime. Batches of used probes then circle back to Vaisala for recalibration, storage and re-use. These refurbished probes retain warranty for the full term of the Circular agreement.


Explaining the signifi cance of the new service, Shan Gao, Director, Global Service Line, said: “As the designer, developer and manufacturer of measurement probes, we are in the best position to maintain them and deliver long-term value for


customers. Our testing, maintenance and calibration capabilities are so rigorous that probes are returned to operation with appropriate certifi cation, and in ‘as-new’ condition. When Vaisala probes are used and maintained according to specifi cations, they can be expected to last for more than a decade.”


By assuming responsibility for probe management, Vaisala Circular delivers long-term peace of mind to customers, providing reliable, accurate measurements and enabling process optimisation and waste reduction to improve sustainability.


The range of measurement parameters included in the Circular service is the widest currently offered in its market and includes humidity, dew point, temperature, carbon dioxide and hydrogen peroxide.


Summarising, Shan Gao said: “Circular is a good example of Vaisala’s determination to develop life-long partnerships, offering customers increased operating uptime and reliable measurements, with predictable instrumentation and maintenance costs.”
