Due to their toxicity and persistance in the environment, Volatile Aromatic Organic Compounds are particularly dangerous pollutants. About their possibile effects on human health, it is important to highlight that some of them are mutagens, terategens or carcinogens. For these reasons, government agencies require these contaminants to be monitored at progressive lower levels. The qualitative confirmation, quantitative accuracy and precision required in current regulations demand for high performing analytical solutions. In this work Master DHS/P&T coupled to Master GC demonstrates that the Purge&Trap is the technique of choice when in need to reach the minimum detectable levels required by law in force.
This is demonstrated in the analysis reported below that shows excellent chromatographic resolution and repeatability with no risk of cross-contamination.
