| Use: | Analyte extraction from soil and ground water samples. Simplified extraction procedures have been developed for field screening of PCBs, PAHs, and pesticides. |
Description:
Solvent extraction procedures involve the use of one more organic solvents, acids, or other chemical substances and measures, such as filtration and centrifugation, to remove and concentrate the analyte of interest.
Analytes:
| 1. Non-Halogenated VOCs | 5. PAHs | 9. Inorganics |
| 2. Non-Halogenated SVOCs | 6. Pesticides/Herbicides | 10. Explosives |
| 3. Halogenated VOCs | 7. Metals | 11. TPHs |
| 4. Halogenated SVOCs | 8. Radionuclides |
