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.

Key learnings from this application note:

1. Understand how headspace sampling can be used to analyse volatile organic compounds (VOCs) in water with minimal sample preparation, saving time and money compared to traditional techniques. 
2. See the comparison of SCION Instruments’ HT3 headspace sampler in static and dynamic mode, discover the differences in results between the modes and the superior signal and signal to noise ratio when using dynamic mode.
3. Discover the importance of using an internal standard and spiked recovery samples to ensure reliability of your system and accurate results.
