Dispersive suspended microextraction

► A novel technique termed dispersive suspended microextraction has been developed. ► Varieties of experiment factors which would affect the experiment results were optimized and selected. ► Compared with other LPME, the most difference is that the restoration step instead of centrifugation process. ► In this technique, the experiment process was divided into two critical steps: the extraction step and the restoration step. ► In the final experiment, this method has been successfully applied in the analysis of wine and tap water samples.
