TOP assay of different materials

Total oxidizable precursors (TOP) assay analysis can be used when estimating the presence of PFAS precursors and intermediates by oxidizing them into stable end-products. The analysis can be combined with traditional PFAS analysis to obtain additional information.

The analysis is suitable for different matrices, for example, water and fire-fighting foams.

Contact the method expert for more information.
