In this webinar we were pleased to have special guest speaker Elizabeth Denly, Vice President, PFAS Initiative Leader & Chemistry Director at TRC. Her presentation discussed delving into the PFAS analytical data, focusing on anomalies found when examining raw instrument data from PFAS lab results, and how they impact the reported PFAS detections and concentrations.
Highlights of this free webinar:
- Common PFAS data anomalies and how they can affect detection and reporting accuracy
- Significance of raw instrument data found in full “Level 4” lab data packages
- Anomalies found in Level 4 data package reviews, including:
- No integration of branched PFAS isomers
- Missing analysis of correct branched isomer calibration standards
- No correction of acid concentrations of select PFAS
- Adding extracted internal standards after the preparation of samples
- No integration of confirmation ions
- Association of extracted internal standards with incorrect or unrelated PFAS
