On-Demand Webinar Recording
Ventia Utility Services (Ventia) in conjunction with the National Measurement Institute (NMI), Eurofins and Australian Laboratory Services (ALS) were awarded the inaugural Australasian Land and Groundwater Association (ALGA) Research and Development Grant to conduct the project ‘Improving Measurement Reliability of the PFAS TOP Assay’.
The per- and poly-fluoroalkyl substances (PFAS) total oxidisable precursor (TOP) assay is an oxidative sample pre-treatment aimed at converting per- and poly-fluorinated non-target PFAS (perfluoroalkyl acid precursors) within a sample into stable target perfluoroalkyl acids (PFAAs) that can be quantified by conventional Liquid Chromatography-Mass Spectrometry-Mass Spectrometry (LC-MS-MS) analytical techniques.
The project involved preparation of four unique PFAS spiked water samples for blind analysis by NMI, Eurofins and ALS.
The results of the analysis were assessed and will be presented as part of this webinar. The webinar will also describe recommendations developed by the project team for successful application of the TOP assay to complex sample matrices and interpretation of results.
This session will be chaired by Charles Grimison from Ventia who will conclude the session with audience driven questions and answers.
