Phenomenex: Identifying and Avoid False Positives During Routine PFAS Analysis
Overview:
- The reporting limit of a method is also dependent upon the consistency of clean blanks and elimination of sporadic contamination.
- Vendors of PFAS consumables need to provide certified, trace level PFAS free products.
- PFAS are everywhere! They are widely used, vendors/suppliers when contacted don't know their processes are using them.
- Since PFAS contamination has become an issue with PFAS analysis all field samples are taken in duplicate, not just field blanks.
- The complete data package and replicates need to be evaluated by the user in order to make sound conclusions and identify false positives.
- Every step there is a chance to incorporate “free-range” PFAS in your sample, minimize the preparation steps
- How PFAS is analyzed at EPA Region 5 Laboratory
Who Should Attend:
- Anyone lab scientists, or managers involved in PFAS Analysis
Key Learning Points:
- Learn how to approach analyzing for PFAS, it is not rocket science like they made it out to be
- Become aware of Sporadic PFAS Contamination
- Understand how to identify false positives
- Require all analysis quality control and samples to be analyzed in replicates to identify false positives.
