Markes International has announced the launch of the world’s first range of thermal desorption (TD) sorbent tubes that allow up to 500 L of ambient air to be sampled for subsequent analysis and detection of PFAS compounds.
With higher volumes of air available for analysis, a wider range of PFAS compounds can be identified, and analysts are able to reach low pg/m3 detection limits for their analysis of PFAS in ambient air. Analysts using TD instead of solvent extraction can remove potential PFAS sources in the sample prep routine (solvents and glassware) that may give inaccurate data.
