Breathing easy: Advanced monitoring of airborne chemical hazards using thermal desorption−gas chromatography
Presented at Pittcon, USA, 2025
Occupational and Environmental Health and Safety (OEHS) monitoring is vital for protecting worker health and communities from airborne chemical hazards. Such hazards, which can be found in everyday work environments or arise from unforeseen events like the 2023 East Palestine, Ohio, train derailment, pose significant health risks even at low concentrations.
Thermal desorption (TD) is an essential tool for monitoring and detecting trace-level, often harmful chemicals such as chemical warfare agents (CWA) and volatile organic compounds (VOCs).
Airborne chemical hazards, can be found in:
- Everyday work environment (Occupational hygiene).
- Home environments (Indoor air).
- Ambient air (Ozone precursors).
- Unforeseen events like train derailments (Near-real-time monitoring).
This poster showcases the various TD–GC workflow solutions for unattended, continuous monitoring, near real-time and off-line monitoring, simplifying the analysis of airborne chemical hazards.
