Automating Liquid–Liquid Extraction with SLE Cartridges

THE CHALLENGE OF CONVENTIONAL LLE

Conventional Liquid–Liquid Extraction (LLE) relies on time-consuming, operator-dependent manual steps—mixing, phase separation, and recovery—making standardization difficult for substantial sample sets.

A SMARTER APPROACH: SUPPORTED LIQUID EXTRACTION

Supported Liquid Extraction (SLE) overcomes these limitations by keeping the same liquid–liquid partitioning principle while streamlining the entire workflow. The aqueous sample is loaded onto an inert support where the solvent passes through to extract target analytes, leaving polar matrix components behind. 

By shifting to this format, SLE eliminates the main operational bottlenecks typical of LLE:

Furthermore, synthetic sorbents recently introduced for SLE provide uniform flow, high reproducibility, and minimal batch variability compared to natural materials.

SLE UNLOCKS AUTOMATION

Because manual handling is fully eliminated, SLE seamlessly integrates into automated workstations, enabling laboratories to achieve:

THE TAKEAWAY

SLE modernizes LLE chemistry into a simpler, automated workflow—boosting lab productivity and reproducibility.
