ABSTRACT

In the US, the current state of monitoring for polychlorinated biphenyl (PCB) compounds relies on a single approved method, EPA method 608.3, which only targets seven Aroclors mixtures. This method is not adequate for estimating PCB contamination in the environment. To address this, the EPA has introduced a new method, 1628, which evaluates all 209 PCB congeners individually using low resolution mass spectrometry detection. Presented here are two methods that meet the performance criteria of EPA method 1628, a method using the traditional carrier gas, helium, and one using hydrogen carrier gas with novel ionization technology optimized for hydrogen.
