Analysis of Trace PFAS in air by TD- GC-MSD

Perfluorinated and Polyfluorinated Alkyl Substances (PFAS) are a group of persistent organic pollutants, infiltrate our environment through various industrial and everyday channels. These sources encompass water-resistant coatings, fire-fighting equipment, and nonstick cookware. Recent report citing that there are around 6000 compounds comes under this category. The main challenge is here to find a way to analyze these components in lowest possible level and there is no single method to analyze all the components of interest.

PFAS

PFAS have become a prominent subject of global regulatory scrutiny across various domains, including drinking water, wastewater, soils, textiles, personal-care products, and more. Air serves as a recognized reservoir for PFAS, transporting them over long distances. To analyze PFAS in the air, a suitable trapping method such as TD (Thermal Desorption) is necessary, while GC/MS (Gas Chromatography/Mass Spectrometry) is the preferred technique for analysis.

Why it is important to analyze the PFAS in Air?

The aim of this analysis is to evaluate the performance of the latest off-the-shelf sorbent tube sampling and automated TD–GC/MS analytical technology for analyzing volatile and semi volatile PFAS.

How to analyze the PFAS analytically?

  • Gas chromatography coupled with mass spectrometry and sampling through Thermal Desorption (Markes International TD100‑xr) is the versatile tool.
  • Excellent system sensitivity and selectivity by selective ion monitoring.
