High-volume collection and rapid sample preparation for thermal desorption gas chromatography-mass spectrometry analysis.
Devices to screen for volatile organic compounds (VOC) are used to check for contraband, environmental hazards, or industrial hygiene. Typically, a surface is swabbed and the sample dissolved in a liquid solvent for testing. This two-step process is time consuming and not suitable in situations where fast screening is needed.
Developed by researchers at the Transportation Security Administration, the High-Volume Sampling Front-End Collection and Thermal Extraction Device (HVST-TED) is a portable, lightweight, and low-cost method for high-throughput testing. Air or surface swab samples are heated to release the sample VOCs, which are pulled through a filter and captured in a commercial thermal desorption tube that can be inserted into any gas chromatography-mass spectrometer (GC-MS) for sample analysis.
