L2000® Soil Reagents

L2000 Reagents for On-Site Analysis of Soil for PCB/Chlorinated Organics

U.S. EPA SW-846 METHOD 9078

The L2000DXT PCB/organic chlorine 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 L2000DXT 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 L2000DXT 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 L2000DXT is (MDL) 3 ppm - 2000 ppm.  Results are displayed on a 7" LCD touch screen and are stored in the internal memory.  Results may also be saved to an external flash drive for easy uploading to an Excel program to make later recall and reporting quick and easy.  

 *Some soils, such as wet clays, can pose an extraction problem. For information on dealing with difficult to solvate soils, please go to L2000 Two-Step Soil Reagents.

Note:  The L2000 soil reagents may used with both the L2000DX and L2000DXT analyzers.
