CAN121: Determination of Polychlorinated Biphenyls (PCBs) in Soils and Solid Waste by Accelerated Solvent Extraction and GC-MS/MS

Instrument Type: GCMSMS

Polychlorinated biphenyls (PCBs) belong to a broad family of synthetic organic chemicals known as chlorinated hydrocarbons. In the United States, PCBs were produced from 1929 until their manufacture was banned in 1979.Although all 209 of the PCB congeners can be synthesized, only about 130 individual congeners have been identified in commercial PCB mixtures at concentrations ≥ 0.05%. The method reported here is applicable for the determination of 32 of the 209 possible PCB congeners in soils, including the dioxin-like PCB (“non-ortho”,“mono-ortho PCB”, and “di-ortho PCB”).

Fast and simple approach for the analysis of benzophenones from breakfast cereal using QuEChERS and a Thermo Scientific TraceGOLD TG-17MS GC column

Instrument Type: GCMS

This work demonstrates the use of QuEChERS as a fast and simple sample preparation approach for the extraction of benzophenones from breakfast cereal. The separation of benzophenone and 4-hydroxybenzophenone was performed on a Thermo Scientific TraceGOLD TG-17MS column with MS detection.
