PCB Congener Testing by CLP Method
ALS Environmental has expanded its capabilities for testing PCB congeners by the EPA CLP method. The Houston laboratory maintains an EPA contract for testing groundwater and leachate samples for all 209 PCB Congeners using the EPA CLP Statement of Work (SOW), CBC01.0.
All PCB congeners are reported through the laboratory information management system (LIMS). No manual calculations or manual flagging are performed on the data. The electronic data reported directly from LIMS matches the hardcopy report exactly.
PCB congeners are tested using HRMS in all sample matrices, including: water, soil or sediment, tissue, industrial products and air. During the 1980s and 1990s, PCBs were most often tested by GC/ECD and were reported as “indicator” PCB mixtures called arochlors. The individual PCB congeners (209 in total) can now be tested by one HRMS method, EPA Method 1668A. Due to the extensive compound list, some congeners cannot be separated and are reported as co-eluted compounds. A total PCB concentration is achieved by summation of the individual and co-eluted compounds.
