Abstract
A laboratory and field test were performed to select and evaluate possible replacement sorbents for sampling volatile organic compounds in stationary sources using SW-846 Method 0030. On the basis of laboratory results, Anasorb 747 was selected for testing in the field using dynamic spiking procedures. This modification of the VOST method uses a single tube containing Anasorb 747 that is preceded by two tubes containing Tenax. The modified VOST method was compared in the field with the VOST method using traditional adsorbents. Both the VOST and modified VOST used a quadruple probe and four similar sampling trains, using the same certified compressed gas cylinder as a source of test compounds. As a general observation, the recovery and precision of most compounds is improved by using the modified VOST procedure.
