Analysis of Volatile Organic Compounds (VOCs) in Water using HS-GC-MS with EPA Method 8260: Static vs Dynamic Headspace

Volatile organic compounds (VOCs) are widely used organic chemicals that readily volatilise and can pose significant environmental and health risks. EPA Method 8260 provides a GC‑MS‑based approach for the determination of VOCs in matrices such as water and soil, with headspace sampling recommended for efficient VOC introduction. This application note validates a VOC analysis method for water using the SCION HT3 headspace sampler coupled with the SCION 8300 GC and SQ 8700 MS, comparing static and dynamic headspace sampling to assess analytical performance.


Extractable Petroleum Hydrocarbon (EPH) Analysis in Water by GC-FID

Monitoring EPH levels in drinking water is therefore critical to ensure safety. Solid Phase Extraction (SPE) is commonly used in sample preparation to isolate target analytes from complex matrices. Using silica-based SPE fractionation, EPHs can be separated into aliphatic and aromatic compounds for analysis. This application can be performed using SCION 8300 or 8500 GC systems, equipped with an 8400 Pro Autosampler, S/SL injector, and FID detector.


Determination of Total FAME and Linolenic Acid Methyl Esters in Biodiesel According to EN 14103

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.


Analysis of NMP in batteries by GC-FID

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 Hydrocarbon (TPH) Analysis in Water by GC-FID Using Hydrogen as a Carrier Gas

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


Analysis of Volatile Organic Compounds (VOCs) in Water using HS-GC-MS (Versa): EPA Method 8260

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
