Thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS) supports the trace-level analysis of contaminants across solid, liquid and gaseous matrices. The application notes in this collection highlight the versatility and sensitivity of the technique through real-world case studies: the analysis of microplastics in salt samples, where direct TD enables quantitation of characteristic polymer markers from microgram residues; the determination of polycyclic aromatic hydrocarbons (PAHs) in water using high-capacity sorptive extraction coupled with TD–GC–MS to achieve ppt-level sensitivity and excellent reproducibility; and the monitoring of volatile fluorinated species from PFAS destruction, leveraging TD preconcentration to allow sub-ppt detection in accordance with US EPA OTM-50.
Together, these studies underscore the core strengths of TD–GC–MS making it an indispensable tool for effective environmental analysis.
