Polychlorinated biphenyls (PCBs) are man-made organic chemicals that were used in many industrial and commercial applications due to their non-flammability, chemical stability, high boiling point, and electrical insulating properties. PCBs do not readily break down once they enter our environment and can cycle between air, water, and soil.

Polychlorinated biphenyls (PCBs) are man-made organic chemicals that were once used in many industrial and commercial applications due to their non-flammability, chemical stability, high boiling point, and electrical insulating properties. PCBs persist in the environment, cycling between air, water, and soil.

This application note describes polychlorinated biphenyl (PCB) analysis based on electron capture detector (ECD) detection and dual-column confirmation approach on the Agilent Intuvo 9000 GC.

2024年10月10日 · Product support is aware of the issue with Python debugging and VS 2022 and is working on a solution. Currently the only workaround is to utilize C# instead of Python, as the debugging for that does work.

We recently had a new 7890B installed at our workplace for PCB analysis using congener pattern recognition to identify the particular Aroclor. Previously we used an old 7890A running MSD Chemstation E02.02.1431 and I thought I could just transfer the run parameters (ie: pressure and oven ramping) to the new instrument.

MassHunter Environmental Quant B.08 Polychlorinated Biphenyls (PCBs) as Aroclors. This technique uses 5 characteristic peaks for quantitation for each Aroclor and either sum the 5 peaks or average the 5 peaks. Was this helpful? Still Need Assistance?

Bond Elut PCB is a specially designed sorbent that allows for the easy extraction of polychlorinated biphenyl (PCB) compounds from various matrices. Desired analytes can be loaded and eluted using a simple, single solvent method before analysis by GC/ECD.

Persistent organic pollutants (POPs) such as polychlorinated dibenzo-p-dioxins (PCDDs), furans (PCDFs) and biphenyls (PCBs) continue to attract interest around the world due to strict regulations in force in many countries. Rapid sample clean up, and analysis are therefore needed for many laboratories processing samples for POPs.
