In this study, the intentional incorporation of an air bubble into a solvent droplet is proposed for fully automated bubble-in-drop microextraction–gas chromatography–mass spectrometric (BID-GC–MS) analysis of selected organochlorine pesticides as model analytes.

By optimizing and fully automating the bubble-in-drop microextraction process, this sample preparation technique, combined with gas chromatography–mass spectrometry (GC–MS) analysis, provides high precision and good figures of merit, as shown for selected organochlorine pesticides in the analysis of tap water and reservoir water samples.
