Field Test of a Generic Method for Halogenated Hydrocarbons: A VOST Test at aChemical Manufacturing Facility Using a Modified VOST Sampling Method

摘要

A field test was performed to evaluate a possible replacement sorbent forsampling volatile organic compounds in stationary sources using SW-846 Method 0030. On the basis of laboratory results, Anasorb 747(Trademark) was selected for testing in the field using dynamic spiking procedures. This modification of the VOST method uses a single tube containing Anasorb 747(Trademark) that is preceded by two tubes containing Tenax(Trademark). The modified VOST method was compared in the field with the VOST method using traditional adsorbents. As a general observation, the recovery and precision of most compounds is improved by using the modified VOST procedure.
