Our PFOS and PFOA isomers analytical standards
These solutions of PFOS (perfluorooctanesulphonic acid) and PFOA (perfluorooctanoic acid ) isomers developed by Wellington Laboratories are certified standards designed specifically for the analysis of PFAS substances.
These specific mixtures are used for:
- Identify and quantify specific branched isomers of PFOS, often present in industrial electrochemical fluorination (ECF) formulations.
- Understanding isomeric distribution in environmental samples (water, soil, biological matrices).
- Trace the origin of contamination (in particular differentiate between ECF sources and telomerisation polymerisation processes ).
- Improving analytical coverage in targeted and semi-targeted methods.
All our CRMs are available as individual solutions of 200 uL in methanol and are ISO 9001, ISO/IEC 17025 and ISO 17034 certified.

Importance of branched isomers
The branched isomers of PFOS and PFOA have toxicokinetic and ecokinetic properties that are distinct from their linear counterparts, influencing their behaviour in the environment and their impact on human health. Differentiated analysis of these isomers is therefore crucial to accurate risk assessment.
