Article Synopsis
- Researchers developed a fast and accurate method to sample and determine aromatic hydrocarbons and certain toxic compounds using common adsorbents like Tenax TA and Carbotrap.
- The study found that Carbotrap C is effective for high molecular weight compounds, while Carbosieve S-III and Tenax TA work well for volatile substances.
- Using thermal desorption not only eliminates the need for solvents but also allows for the reuse of the adsorbent tubes; however, a combination of different adsorbents is needed for effective sampling across a range of compounds.
