Is PFAS contamination a problem when using TD–GC–MS systems?
Monitoring volatile PFAS in air demands exceptionally clean analytical workflows – but how can you be sure your instrumentation isn’t contributing background contamination?
This Instant Insight addresses a common concern in trace-level PFAS analysis: contamination from analytical equipment, particularly from fluoropolymer components such as O-rings and seals. It presents reassuring data from real-world testing showing that Markes' TD systems do not introduce detectable PFAS contamination – even when analysing down to the pg/m³ level using selective reaction monitoring (SRM) on GC–MS/MS.
You’ll also discover why thermal desorption (TD) offers major benefits for PFAS analysis, including sample re-collection, compatibility with air canisters and sorbent tubes, and advanced automation features that ensure clean, confident results.
