PFAS testing: Precise and efficient sample and standard preparation for accurate results

METTLER TOLEDO, a global leader in precision instruments, has published a new application note on PFAS testing and analysis, highlighting its expertise in accurate and efficient sample and standard preparation. 

PFAS (per- and polyfluoroalkyl substances), also known as ‘forever chemicals’, have seen widespread use in products like non-stick cookware, textiles, food packaging, and firefighting foams. However, PFAS have become an increasing concern due to their bioaccumulation in the environment (water, soil, air, and food sources). Mounting evidence of significant health risks associated with exposure at high levels, including cancers, liver damage, and developmental issues, coupled with increasing public awareness, is driving monitoring programs and stricter regulations worldwide.

The EU Regulation 2023/915 set stricter maximum limits on PFAS in food products, and the European Commission ban on PFAS in portable fire extinguishers comes into force from October 2026. France has prohibited PFAS in consumer goods from January 2026. 

As a result, existing testing laboratories with limited capacity face growing demands for accurate, sensitive and reliable PFAS testing at increasingly low concentrations. New analytical methods are being developed using LC-MS/MS, and other sophisticated high-resolution spectroscopy techniques.

How can METTLER TOLEDO support PFAS testing? 

METTLER TOLEDO is responding to this challenge with innovative weighing and sample preparation solutions specifically designed for PFAS analysis. The recently published application note outlines how precise sample and standard preparation is crucial for achieving the ultra-low detection limits required by modern regulatory standards.

METTLER TOLEDO’s XPR balances (analytical, micro, ultra-micro) and the XPR Automatic Balance offer precise and accurate weighing of small amounts of PFAS reference materials, essential for generating accurate calibration standards. Automated dilution streamlines the preparation of multiple concentration levels, enhancing reproducibility and reducing errors. Combined with LabX software, to integrate weighing data with laboratory workflows, traceability and compliance with quality standards can be ensured.

METTLER TOLEDO’s precise weighing and dilution solutions, with automation and digitalisation options help testing laboratories meet evolving regulations, improve throughput and accuracy, to protect public health.
