This work is focused on the development of a clean-up method with the AZURA® GPC Cleanup system to purify soil sample extracts before analysis. It was found that GPC cleanup is very useful to remove interferences from extracted soil samples before GC-MS/MS determination of semi-volatile organic compounds, like Polycyclic Aromatic Hydrocarbons. Moreover, the described method enables to perform an automated clean-up procedure and hence to purify many samples efficiently.
