Field screening of volatile and semi-volatile organic pollutants using a heated, portable micro gas chromatograph
- Microsensor Technology, Inc., Fremont, CA (United States)
A heated, portable silicon micromachined gas chromatograph was designed, developed and recently utilized in the characterization of volatile and some semi-volatile organic compound distribution in soil at a site in the Midwest. The use of this system in the field allowed for the rapid, on-site characterization and field screening of gasoline range VOCs and semi-volatiles (e.g., benzene, toluene, ethylebenzene, and xylene; and naphthalene) and chlorinated hydrocarbon solvents in soil and assisted in the geological mapping of environmental hot spots. The sample inlet and introduction system of the micro GC is heatable to 110 C to further extend the application range of the micro GC to samples with high moisture content, high concentration of condensable vapors, and semi-volatile compounds. Data will be presented on the use of the heated system in the characterization of the site with details provided regarding the advantages of individual compound characterization, sampling for screening purposes, and environmental screening in the field (to locate hot spots) and in mobile laboratories (to prevent overloading of GC/MS systems).
