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.

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.
