A chromatogram showing the separation of some fatty acids monitored with the spray impact detector is shown in figure 11. The high sensitivity is clearly indicated. This detector has not been developed commercially but remains an interesting detecting principle based on a well-established natural phenomenon.

Direct current amperometric detector in a thin-layer configuration equipped with a single GCE was used for the determination of fenitrothion and its main metabolites in environmental water samples [164], In this work, the combination of SPME treatment with HPLC with on-line DAD and ED allowed to carry out environmental studies which monitored the impact of fenitrothion after aerial or spray applications.
