Abstract

The paper gives results of a volatile organic analysis (VOC) compositing study conducted by the U.S. Environmental Protection Agency (EPA) in early 1994. In these studies individual grab samples of real-world effluent were collected over the course of a day. These samples were analyzed spiked or unspiked, composited and individually, by isotope dilution GC/MS, using Revision C of EPA Method 1624. The objective was to compare the mathematical average of the results from analysis of the individual grab samples with the result of the analysis of the composite sample to determine if bias occurred in the compositing process.
