VOCs combined sorbent tube sampling tube
Description
The VOCs multi-bed adsorbent sampling tube is a high-performance consumable designed specifically for the collection of volatile organic compounds (VOCs), widely used in fields such as environmental monitoring, industrial hygiene, and indoor air quality testing. Constructed from high-quality stainless steel (304 or 316L), the tube measures ¼ inch × 3½ inches (6.35 mm O.D., 89 mm length) and features optional sealing caps made of copper or PTFE.
This product strictly complies with the HJ 734-2014 standard ("Stationary source emission—Determination of volatile organic compounds—Solid-phase adsorption-thermal desorption/gas chromatography-mass spectrometry") and the EPA TO-17 standard. It offers three standardized adsorbent combinations (Combinations 1, 2, and 3) capable of efficiently capturing VOCs ranging from C₃ to C₁₆, making it an ideal choice for monitoring stationary source emissions, ambient air, and the 57 ozone precursors associated with PAMS (Photochemical Assessment Monitoring Stations).
