A field test waste performed to evaluate a possible replacement sorbent 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 dynamic spiking procedures. The 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 absorbents. Both the VOST and modified VOST used a quadruple probe and four similar sampling trains. Known amounts of the analytes were introduced into the 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 procedures.
