| Figure 2: Schematic description of the analytical method used in the current study. Extraction of VOCs was conducted using a thin film coated on an aluminum rod (TFME-AR). Sampling options used with the TFME-AR included (a) HS extraction and (b) direct extraction from the liquid (aqueous) sample. Thermal desorption from the solid phase was performed in a Curie point injection device. Finally, the extract was introduced in the GC–MS for separation and tentative identification. |
