Development of a portable field monitor for PCBs. Final report
With the advent of recent regulations and those yet pending concerning allowable concentrations of polychlorinated biphenyls (PCBs), personnel in all aspects of the electric power industry, analytical support personnel, and those in the regulatory functions themselves have realized that the PCB problem, as well as these associated regulations, has far surpassed available monitoring capability. In short, detailed, stringent regulations are being set for contamination levels where no accepted ASTM procedure or instrumentation exists. The largest PCB problems occur in the form of PCB-contaminated oil in field transformers and storage containers, and pure askarel in transformers and capacitors. The most immediate need for a portable field instrument would be for use under PCB spill conditions. Portable monitors based on the principles of photoionization detection (PID) and infrared spectroscopy (IR) have been adapted and evaluated for this purpose. The latter includes both flow cell and horizontal multiple internal reflectance (HMIR) sampling configurations. Extensive work has also been performed on solvent-solvent and solvent-soil extractions, as well as PCB adsorption on packings, for use under spill conditions.
