What is it about?
This work proposes the novel overcoated fiber (PDMS/DVB/PDMS) as a greener strategy for analysis by direct immersion solid-phase microextraction in vegetables The robustness and endurance of this new coating were investigated by direct immersion extractions in raw blended vegetables without any further sample preparation steps The PDMS/DVB/PDMS coating exhibited improvements in terms of extraction capability and in the cleanability of the coating surface

Why is it important?
To date, DI-SPME has not yet been extensively explored in food analysis. SPME has yet to realize its full potential due to the complexity of the studied matrices, which have in the past limited SPME methodology in this field to mostly headspace approaches. Indeed, for analysis of complex matrices, SPME is generally preceded by an extraction step and suitable reconstruction of the extract in an aqueous medium. This work demonstrate the superior performance of the novel overcoated fiber for analysis by direct immersion in vegetables. This work demonstrate that the SPME-OC can be used for analysis of pesticide
