The Benefits of Hydrogen Carrier Gas in PCB Analysis

Polychlorinated biphenyls (PCBs) are a class of persistent, bioaccumulative and toxic environmental pollutants that were banned from sale in the 1970s due to their detrimental impact on the environment.

Gas chromatography coupled to mass spectrometry (GC–MS) is considered an extremely reliable tool for PCB analysis but typically relies on helium as a carrier gas. This leaves laboratories reliant on an increasingly expensive and difficult-to-source gas. 

This application note demonstrates how hydrogen carrier gas can be used in place of helium for GC-MS/MS analysis of PCBs, giving laboratories greater flexibility and ensuring sustained, cost-effective operations.
