The National Environmental Monitoring Conference (NEMC) is the largest conference in North America focused on environmental measurements.
Battelle is proud to be participating in the 2019 event. We have decades of experience when it comes to environmental concerns. Right now, one of our major focus areas is per- and polyfluoroalkyl substances (PFAS). We're at the forefront of PFAS research, conducting urgently needed research to better understand the fate and transport of PFAS and minimizing environmental and human health concerns.
Battelle PFAS Laboratory Director Jonathan Thorn will present during a Thursday morning session on the Characterization of Polyfluoroalkyl Substances in the Environment.
Navigating the Complexities of PFAS Analysis, a Laboratory Perspective
Thursday, Aug. 8, 2019 | 11 a.m.
The analysis of PFAS continues to be an evolving landscape, with ever-changing methods, method quality objectives and target analyte lists. Beyond these changes, complex sample matrices, often with co-contaminants, requiring rapid turnaround add to the complexity of these analyses.
In an environment driven by commodity analytical work for the lowest cost, how does a laboratory navigate the complexity of PFAS analytical work?
This presentation will cover:
- Background sources of PFAS contamination and the need for trace-level analysis for field samples
- Detection limits, limits of detection, and limits of quantitation – is there such a thing as “too low?”
- Navigating state level accreditations for unregulated contaminants
- Certified pre-cleaned bottles and PFAS free water for field work
- Sample volumes, sample counts, and containers to be requested from field sites
- Levels of contamination and sample pre-screening, is there a value to pre-screening and does it outweigh the costs?
- Sedimentation levels in non-potable water samples – best practices for handling high solid content waters
- Availability of published methodology and suitability of methods for QSM Table B-15 analysis
- Extraction and analysis of complex matrices, including environmental tissues, crops, and other matrices
- Applying GC/MS criteria to LC/MS/MS technology
- Final data reports, fitting LC/MS/MS data into a CLP report world
