This application note outlines a robust GC‑ECD method for the determination of polychlorinated biphenyls (PCBs) in soil using the SCION 8300/8500 GC platform with an 8400PRO Autosampler. Using an unbuffered QuEChERS extraction and a SCION‑5MS column, the method delivers excellent linearity, precision, and recovery across 14 PCB congeners. Detailed validation demonstrates reliable performance with no PCBs detected in the analysed soil samples. This workflow provides an efficient, cost‑effective solution for routine PCB monitoring and environmental compliance testing.

Understanding and monitoring persistent organic pollutants in soil is essential for protecting both environmental and human health. In this application note, we demonstrate how the SCION GC-MS platform delivers precise, reliable analysis of PCBs and PAHs using an efficient QuEChERS sample preparation workflow.

The analysis of residual pesticides in food is critical to protecting consumer health and ensuring compliance with global regulatory limits. This application note demonstrates the determination of pesticide residues in grapes using gas chromatography–mass spectrometry (GC-MS) with a single quadrupole detector.

Monitoring organophosphorus pesticides in water is essential to protect human health and ensure regulatory compliance. This application note demonstrates the analysis of organophosphorus (OP) compounds in water in accordance with US EPA Method 8141B, using gas chromatography with a nitrogen-phosphorus detector (GC-NPD).

BTEX compounds are key indicators of petroleum-related water contamination and require sensitive, reliable analytical methods to meet environmental and regulatory demands. This application note demonstrates the robust determination of benzene, toluene, ethylbenzene, and xylene (BTEX) in water using the SCION 8300 or 8500 GC.

Solvents are widely used during the synthesis of many pharmaceutical products. It is not always possible to remove all solvents from the final product, hence it is important that all products are tested for residual solvents.
