Overview

Demonstrates advanced analysis of PFAS in environmental waters, suggesting a robust method for commercial use.

Key Points

  • The aim is to develop an efficient and reliable method for analyzing PFAS in environmental waters.
  • Developed a liquid chromatography tandem mass spectrometry method for 40 PFAS.
  • Conducted comparison of automated and manual solid phase extraction techniques.
  • Analyzed water samples from six natural sources in the Baltimore-Metro area.
  • Achieved excellent linearity with r² values greater than 0.997 for all PFAS analytes.
  • Limits of detection ranged from 0.2 to 100 ng/L, with quantification limits from 1 to 350 ng/L.
  • Recovered PFAS from automated extractions ranged from 92.0% to 105.0%, while manual ranged from 67.0% to 109.0%.
  • Seven of the forty PFAS were detected in at least one sample from the analyzed water sources.
