The present application note continues with the series“Determination of Volatile Organic Compounds (VOCs) inWater”. In Part 1 (AN_107)  the determination of chlorinated VOCs was covered , while this part will be focused on the analysis of aromatic VOCs. A mixture containing U.S. EPA Method 502.2 targeted aromaticVOCs was analyzed by means of Dynamic Headspace-GasChromatography (DHS-GC). As described in Part 1, the headspace sampling system consists of the MASTER DHS Dynamic Head Space Sampler, combined with the MASTER AS Automatic Sampler, operated in “purging mode”, according to the above cited EPA method . The extracted VOCs are then analyzed by GC using a Flame Ionization Detector (FID).
The obtained results show that the Dynamic Headspace sampling technique fulfils the requirements for reliable determination of aromatic VOCs in water. Detection limits and calibration results are presented for each standard compound.
