Powertech Labs has been helping industries meet regulations by providing accurate polychlorinated biphenyl (PCB) analysis for over 30 years.
Though the manufacturing and sale of PCBs has been banned since 1977, these persistent organic pollutants are still found in many pieces of electrical equipment in service today. Due to the chemical stability of PCBs, they are known to accumulate in the environment and food chain. It is required by law to avoid and report release of PCBs into the environment. Powertech can help determine concentrations of PCBs before disposal of equipment or oil, after an accidental spill, or to help you meet in-service equipment regulations. With a team of experienced technicians, Powertech is able to offer PCB analysis of various sample types:
- Insulating Oil
- Waste Oil
- Electric Cables
- Solid Materials
With proven accuracy and reproducibility, Powertech’s PCB analysis method has been ISO 17025 accredited since 2006, and is routinely audited by the Standards Council of Canada. Furthermore, our laboratory technicians complete ongoing proficiency testing through the Canadian Association for Laboratory Accreditation (CALA).
Powertech performs PCB testing in accordance with published, industry standard reference methods. Focusing on products historically sold in Canada, samples are typically analyzed for the most common PCB Aroclors: A1242, A1254, and A1260. Other Aroclors such as A1248 are available upon request. Using a gas chromatography system coupled with a micro-electron capture detector (GC-ECD), reporting limits for common matrices are as follows.
The Canadian PCB Regulation (SOR/2008-273) requires action to be taken at two key concentration levels: 2 mg/kg and 50 mg/kg. Analytical uncertainties at these concentrations are listed in the table below.
Powertech’s Applied Chemistry laboratories have more than forty years’ experience in testing, consultation, and applied research in the chemistry of insulating liquids, gases, and solids used in electrical equipment.
