L2000DX Reagents for On-Site Analysis of Soil for PCB/Chlorinated Organics
U.S. EPA SW-846 METHOD 9078
The L2000DX PCB/Chloride analyzer is a field portable instrument that can quantify chlorinated compounds in *all types of soil. Soils contaminated with PCBs, chlorinated solvents, or chlorinated pesticides/herbicides can be tested on-site in just 10 minutes. Screening with the L2000DX system can greatly reduce the number of samples requiring expensive, time intensive laboratory analysis allowing for faster decision making in the field regarding delineation, excavation, remediation.
Collected soil samples are extracted and reacted with a sodium reagent to strip the covalently bonded chlorine from the analyte(s) converting it to inorganic chloride. The resulting chloride is then detected and quantified using a chloride ion specific electrode. The L2000DX then mathematically converts the chloride reading to the equivalent concentration of the target analyte based on the percent chlorine associated with the analyte. Note: Inorganic chloride, e.g. road salt, will not interfere with the test. Conversion programs are available for all major Aroclors and most common chlorinated solvents and pesticides. Custom conversion programs can be built for less common analyte(s) not included on the L2000DX menu, instructions are included in the user manual.
The usable result range for the L2000DX is (MDL) 3 ppm - 2000 ppm. Results are displayed on the LCD screen and printed by the on-board thermal printer. The printed record can be customized to include project specific information such as site location, sample ID, technician’s name, etc. The L2000DX also stores the test data for later recall or reprinting.
*Some soils, such as wet clays, can pose an extraction problem. For information on dealing with difficult to solvate soils, please go to L2000DX Two-Step Soil Reagents.
Also available in "Bulk Packs" of 200 tests. For information and pricing, please contact a Dexsil sales representative at firstname.lastname@example.org.
