AI Technical Summary
Existing microextraction technologies have limitations in terms of mass transfer efficiency and extraction rate. In particular, countercurrent microextraction systems are complex, costly, and have poor stability, making it difficult to meet the requirements for efficient separation and miniaturization.
A high-throughput fully automated liquid-liquid countercurrent microextraction system was designed, which adopts an array-type countercurrent microextraction combination, combining a filtration unit, a countercurrent microextraction unit and a fluid power unit. The liquid is discharged through a capillary to form tiny droplets and countercurrent flow, which increases the liquid-liquid contact area and time, and achieves efficient mass transfer.
It achieves high-throughput, automated liquid-liquid countercurrent extraction, significantly improving extraction recovery and reproducibility. It has a compact structure, low cost, and is suitable for laboratory automation platforms, with mass transfer efficiency improved by more than 20 times.
