Compliance with biodiesel quality standards requires accurate determination of total fatty acid methyl ester (FAME) content and linolenic acid methyl esters. This application note demonstrates the use of a GC‑FID method in accordance with EN 14103 for the analysis of B100 biodiesel, using a SCION gas chromatograph equipped with a split/splitless injector and a SCION‑WAXMS column. The method delivers reliable quantification across C14–C24 methyl esters with excellent repeatability.

N‑methyl‑2‑pyrrolidone (NMP) is a critical solvent in lithium‑ion battery manufacturing, but residual NMP in electrode materials presents both performance and regulatory challenges. This application note describes a validated GC‑FID method for the quantification of residual NMP in battery electrodes, developed to support quality control in the manufacturing process and reduce exposure. Nitrogen was used as the carrier gas within this application due to its ability to be produced renewably and to avoid current issues over helium supply

Total petroleum hydrocarbons (TPH) represent a broad range of compounds derived from crude oil that pose potential environmental and human health risks when present in water. This application note describes the development and validation of a GC‑FID method for the determination of TPH in water using hydrogen as an alternative carrier gas. The method demonstrates excellent precision and specificity across a wide carbon range, while offering a practical response to ongoing helium supply constraints and supporting more sustainable laboratory operation

Effective monitoring of VOC contamination in water requires sensitive, reproducible and compliant analytical techniques. In this application note, we demonstrate how the SCION Versa headspace sampler coupled with GC‑MS meets the requirements of EPA Method 8260 for water analysis. The method achieves excellent performance in terms of linearity, precision and recovery, offering laboratories a dependable solution for VOC determination

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.
