Analysis for PFAS (PFOS, PFOA, PFHxS, etc.)

Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), which are polyfluoroalkyl substances (PFCs / PFAS), are difficult to decompose in the environment and have a high accumulation potential. They are subject to various international regulations, including the Stockholm Convention on Persistent Organic Pollutants (POPs)*.

Fujifilm Wako provides pretreatment columns, solvents, and analytical standards that can be used to analyze PFAS (PFOS, PFOA, and PFHxS).

* POPs
Chemical substances that are highly toxic, persistent, bioaccumulative, mobile over long distances, and have adverse effects on human health or the environment are called Persistent Organic Pollutants (POPs). POPs are required to eliminate / limit, reduce emissions, and properly dispose of waste.

3 PFAS Mixture Standard Solution

Fujifilm Wako provides mixture standard solutions and internal standard solution (13C labels) for PFHxS, PFOS, and PFOA which are compounds subject to JP Water Quality Act. Both are mixture standard solutions with clear concentration value of linear PFAS.

Features

✔ Mixture standard solutions with clear concentration value of linear PFAS!
