Thermal Desorption Featured in Restek Newsletter

June 15, 2008
Article

The current issue (2008.1) of Restek?s e-newsletter, ?The Restek Buzz,? includes an article that summarizes the key advantages of thermal desorption versus solvent extraction in air monitoring applications.

The current issue (2008.1) of Restek's e-newsletter, "The Restek Buzz," includes an article that summarizes the key advantages of thermal desorption versus solvent extraction in air monitoring applications. Thermal desorption is a gas extraction technique in which sorbent tubes that have been exposed to air samples are heated in a flow of carrier gas. Trapped vapors are desorbed into the carrier gas flow and are transferred into a gas chromatography-mass spectrometry (GC-MS) system. According to the article, thermal desorption offers better sensitivity, desorption efficiency, and reproducibility compared with charcoal-carbon disulfide systems.

HPLC 2025 Preview: Functionalized Monoliths as Selective Sample Preparation Materials

Nathalie Delaunay;Audrey Combès;Valérie Pichon
May 16th 2025
Article

Analyzing trace compounds from complex samples often requires purification and pre-concentration, and online coupling of solid-phase extraction (SPE) with liquid chromatography (LC) helps minimize analysis time and solvent/sample use. Monoliths with large macropores are ideal for this coupling due to their low back pressure and versatility in various formats.
