L2000® Two-Step Soil Reagnets

L2000DX Two-Step Extraction Recommended for Hard to Extract Wet Clays

Soils, such as wet clays, pose an extraction problem with most extraction solvents on the market today. If the extraction solvent cannot solvate the soil and remove the contaminant efficiently, an underestimation of the contaminant will occur. Dexsil has developed a "Two-Step Extraction Method" that allows difficult soils to be solvated efficiently for accurate and reliable results. In a recent study, the two-step method was used to extract PCB from lacustrine clay. When compared to a soxhlet extraction method, the 2-step method had an extraction efficiency of >78%. 

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.
