Weck is currently capable of determining the concentration of 25 of the 209 possible congeners of PCB at 10 ng/L (ppt) levels. The congeners range from 2,4'- Dichlorobiphenyl to Decachlorobiphenyl. The target compounds are removed from water samples by automated Solid Phase Extraction (SPE) and are analyzed by electron impact ionization GCMS in the Selected Ion Monitoring (SIM) mode.
