Abstract A new solution for the passive monitoring of Volatile compounds to sub-PPB levels in air is presented. New adsorbent based sampling devices called SorbentTM Pens are used to passively collect air samples for 24 hours to 2 weeks, depending on the sensitivity and period of time weighted averaging desired. For this study, Carbopack X […]
Canister sampling and analysis for measurement of volatile chemicals is finding use in a growing number of diversified applications. This has required air laboratories to accommodate an even wider dynamic range of sample concentrations, and a growing list of compounds to include those once thought to be incompatible with canister sampling techniques.
