MPS Automated Membrane Extraction

Product catalog summary

Overview
The GERSTEL MultiPurpose Sampler (MPS) Membrane Extraction option provides an automated solution for extracting and analyzing samples with complex matrices. This technology eliminates the need for extensive manual clean-up steps, making it efficient for challenging sample types.

Membrane Extraction Technology
The technique involves extracting organic analytes across a polymer membrane from a liquid sample phase into a liquid solvent phase. This method is particularly effective for samples with solids, suspended particles, charged compounds, or high molecular weight compounds, and for sample-solvent combinations where phase separation is difficult.

Advantages

Facilitates easy extraction of complex matrices.
Provides excellent sample cleanup.
Reduces solvent consumption.
Enables high sample throughput with full automation.
Offers an easy upgrade option for existing MPS 2/3 systems.

Procedure
The process is straightforward: a liquid sample is placed in a vial, a conical membrane is inserted, and the vial is capped. The MPS automates the rest, including solvent addition, vial heating and agitation, solvent extract withdrawal, and final injection for GC or LC analysis.

Software Integration
The GERSTEL Maestro Software with integrated PrepBuilder functions allows for quick setup of the complete membrane extraction and sample injection procedure.

MPS Membrane Extraction Option* The GERSTEL MultiPurpose Sampler (MPS) Membrane Extraction option enables automated extraction and chromatographic analysis of samples with very complex and challenging matrices. Extensive manual clean-up steps can be eliminated. The Membrane Extraction technique is based on extraction of organic analytes across a polymer membrane from a liquid sample phase into a liquid solvent phase. Since the liquid phases are not in direct contact with each other, liquid-liquid extractions of dirty matrices such as samples containing solids, suspended particles, charged compounds...
