Volatile organic compounds (VOCs) are a group of chemicals that readily volatilise at low temperatures from various liquids and solids. VOC’s can be released as organic chemicals through an extensive list of sources including common every day products which 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.

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.
