GERSTEL Liquid-Liquid Extraction

Liquid–liquid extraction is a separation technique that transfers compounds between two immiscible solvents, typically a water phase and an organic solvent. By mixing the phases, target substances move into the solvent in which they are more soluble. The liquids are then separated, followed by removal of the solvent to isolate the product.

During sample preparation, analytes are moved from a complex matrix into a cleaner solvent and can be enriched by using a smaller solvent volume. This process is usually performed manually and is often labor-intensive. 

Automated Filtration using the MPS

The GERSTEL MultiPurposeSampler (MPS) automates even complex liquid–liquid extractions using its versatile modules. Automation reduces manual workload and minimizes exposure to hazardous organic solvents. Individual extraction steps can be freely combined and integrated with other MPS sample preparation modules, enabling a seamless workflow. The final step can include direct injection into a connected analytical system for fully automated processing.
