Quantitative determination of semi-volatile polychlorinated biphenyls (PCBs) using TD–GC–MS

Application Note 137

Polychlorinated biphenyls (PCBs) enter the environment from legacy sites for hazardous waste, from electrical equipment and construction materials, and by the improper disposal of consumer waste. Their tendency to persist in the environment and their known negative health effects has led to growing concern from regulators, which in turn has drawn attention to the need for reliable and practical analytical methods.

This application note describes the performance features that enable Markes’ thermal desorption systems to be used for the GC–MS analysis of trace-level polychlorinated biphenyls in air.
