“…Moreover, the nonspecific adsorption on the channel surface can be minimized and the consumption of the extractants can be adjusted easily. Chen et al [15] employed the droplet flow microfluidic LLE to extract lowconcentration rare earth elements at larger phase ratios and confirmed its advantages on fast phase separation and low extractants consumption. To figure out the similarities and differences of LLE at different scales, Nelson et al [16] compared the extraction of Nd(NO 3 ) 3 from the aqueous phase to the organic phase of dodecane having tributyl phosphate in laboratory-scale equipment and droplet flow microfluidic chip device.…”

Sample preparation turns out to be one of the important procedures in complex sample analysis by affecting the accuracy, selectivity, and sensitivity of analytical results. However, the majority of the conventional sample preparation techniques still suffer from time‐consuming and labor‐intensive operations. These shortcomings can be addressed by reforming the sample preparation process in a microfluidic manner. Inheriting the advantages of rapid, high efficiency, low consumption, and easy integration, microfluidic sample preparation techniques receive increasing attention, including microfluidic phases separation, microfluidic field‐assisted extraction, microfluidic membrane separation, and microfluidic chemical conversion. This review overviews the progress of microfluidic sample preparation techniques in the last 3 years based on more than 100 references, we highlight the implementation of typical sample preparation methods in the formats of microfluidics. Furthermore, the challenges and outlooks of the application of microfluidic sample preparation techniques are discussed.
