Polychlorinated biphenyls (PCBs) are highly toxic industrial compounds that are chemically stable and non-flammable with have high boiling points and electrical insulating properties.

These chemical properties made PCBs popular for a variety of industrial applications, including use in electrical transformers, hydraulic fluids and lubricants.

PCBs are slow to break down and can persist in the environment posing serious health risks to humans with continued low levels of exposure. Although PCBs have been banned for many years the problem of PCB contamination is widespread.

We are pleased to offer many PCB reference standards for your analysis needs.
