Technology Description: | |
The L2000 Analysis System is a field portable device that allows the user to analyze for PCBs and other chlorinated organic material in either soil or oil. Oil samples are run directly and soil samples are reacted after the sample has been extracted with an organic solvent. All sources of inorganic chloride are removed from soil extracts before proceeding with the analysis. The sample (either the oil or the soil extract) is reacted with a sodium reagent which removes chlorine from any PCBs or other chlorinated organics that are present. The resulting chloride ions are then extracted into an aqueous phase where they are quantified by the L2000's ion specific electrode. By pre-selecting an analytical mode such as Aroclor 1242 or Aroclor 1260 the user can customize the output for specific analytes. The L2000 translates the amount of chloride sensed into parts per million PCB (or other analyte) and displays directly in ppm on the LCD read out the concentration of the analyte contained in the original sample. The range of the instrument is from 2 to 2000 ppm, and samples can be analyzed in 10 minutes. This quantitative method can be performed in the field for less than $10 per sample. |

Performance Status/
Limitations: | |
Performance Status:
The L2000 has been in use in the field since 1989. It has been used worldwide with great success by both those experienced in analytical methods and those with no experience. Users include utilities, consulting firms, engineering firms, enforcement agencies, environmental groups and federal agencies. It has been tested in EPA's SITE program and has been submitted to the EPA Office of Solid Waste for inclusion in the SW-846 methods manual. Several technical papers on the L2000 are available from Dexsil on request.
Limitations:
The L2000 works by testing the soil or oil for total organic chlorine content. This means that when looking specifically for PCBs, the operator needs to be aware that other chlorinated organic compounds, if present, may interfere and result in a positive bias. Inorganic chloride such as that from sodium chloride will not interfere.
Results from the soil samples that contain moisture will be reported by the L2000 on a wet weight basis. This means that for a sample containing 10% moisture by weight, the results from the L2000 will read 10% lower than the results from the sample on a dry weight basis. If the samples are dried prior to analysis, the results will, of course, be on the dry weight basis.
