Abstract:
This poster presents the analysis of volatile organic compounds (VOCs) using thermal desorption coupled with GC-MS, leveraging hydrogen as carrier gas. Hydrogen offers faster separations, improved chromatographic resolution, and reduced operating costs compared to helium, while supporting laboratories in meeting sustainability goals. The method achieves sub-ppb detection limits for target VOCs with excellent linearity and reproducibility. Results confirm that hydrogen does not compromise GCMS data quality and enables high-throughput analysis crucial for environmental monitoring. This approach provides a robust, cost-effective, and future-proof solution for laboratories facing helium supply challenges.
