Perfluoroalkylated and polyfluoroalkylated substances (PFAS) are causing increasing concern because of their recognised impact on human health and the environment. Faced with the challenges posed by PFAS, it is essential to analyse these substances using analytical standards in order to guarantee public safety. This is why BCP Instruments is the only company in France and Belgium to offer a wide range of CRMs (Certified Reference Materials) compatible with EPA-1633, prepared by Wellington Laboratories.

A complete range dedicated to environmental analysis

To meet the challenges of precision and compliance, Wellington has developed several PFAS mixtures. These solution/mixtures, with a chemical purity of over 98%, contain linear and branched isomers, faithfully reflecting the technical materials. They are therefore designed to guarantee optimum analysis results.

In addition, this initiative complies with the strict methods of the US EPA (1633, 533 and 537.1), which require accurate identification and quantification of isomers for a complete assessment of PFAS exposure.

The advantage of prepared blending solutions

For analytical laboratories, using mixtures of isomers prepared by Wellington offers several advantages:

  • Save time and resources: ready-to-use mixes allow laboratories to concentrate on analysis without having to prepare their own mixes.
  • Regulatory compliance: these mixtures comply with the strict requirements of standard methods.
  • Reliable results: high purity and precise proportions guarantee reproducible and reliable data.
