Adapting the Brueel and Kjaer Multi-gas Monitor Type 1302 to measure selected volatile organic compounds (VOCs) in soil
- Oak Ridge National Lab., TN (United States)
The Brueel and Kjaer Multi-gas Monitor Type 1302 can simultaneously measure up to five different volatile organic compounds (VOCS) in a single air sample by using optical filters combined with a photo acoustic detector. The monitor has previously been validated to measure VOCs in water, by purging aqueous samples with air into Tedlar bags. The method used to measure VOCs in water has been adapted for use with soil. Soil samples are diluted with water and VOCs are purged with air from the resulting slurry into a Tedlar bag. The contents of the bag are then analyzed with the Multi-gas monitor. Data have been generated for the measurement of chloroform, trichloroethylene, tetrachloroethylene, carbon tetrachloride, and acetone. The method is linear for these VOCs from approximately 1 to at least 128 {micro}g/g of soil (ppm). There is no measurable cross interference of these VOCs when more than one of the compounds is spiked into a single soil sample. Contaminants other than those being measured may interfere with detection of these VOCS, so some prior site characterization is required. The method is easy to perform, rapid, reproducible, and sensitive enough for field screening applications.
