A demonstration of how TD–GC–MS/MS enables measurement of per- and polyfluoroalkyl substances (PFAS) in air at concentrations as low as 2 pg/m3.

Wednesday 19th October 2022 at 9am EDT | 2pm BST | 3pm CEST Join this webinar from Markes International to hear Dr. Ariel Geer Wallace from the US EPA discuss her research into methods of PFAS destruction, and the technology she is using to benchmark the effectiveness of thermal treatment techniques.

Tue, Aug 9, 2022 11:00 AM EDT In this webinar, we explain how to analyse a wide range of volatile organic impurities from hydrogen fuel in a single run using “hydrogen-certified” thermal desorption with GC–MS and specific detectors ( SCD), complying with relevant global standards. Thanks to optimised preconcentration technology, the technique has proven to be more sensitive than alternative techniques and systems, while the ability to run both on-line and off-line samples gives ultimate flexibility to the analyst.

Identification of impurities in hydrogen fuel supplies was demonstrated using an on-line thermal desorption–GC–MS system, which complied with various standard methods.
