Passive Collection of Volatile Compounds in Air using a Novel Adsorbent Sampler with Direct, Rapid Injection into a Capillary GCMS without Secondary Focusing

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 […]

Improved Performance And Dynamic Range For EPA Method TO-15 using the Entech 7200 and Agilent 7890B/5977 GCMS

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.

Sampling with MiniCans and Bottle-Vacs

Canisters offer a simple and highly effective means of measuring volatile chemicals in air ranging from PPM to sub-PPB levels.
