Solid Phase Extraction

Performing Solid Phase Extraction (SPE) manually can be time consuming and nerve-racking, especially when recovery and reproducibility are lacking due to sample variability. If Solid Phase Extraction (SPE) can be reliably automated, it becomes a much more efficient and reproducible process.

The GERSTEL Multi Purpose Sampler (MPS) with Automated SPE Option for standard cartridges provides several benefits compared with manual Solid Phase Extraction:

  • Improved recovery, precision and reproducibility
  • Maximized sample throughput by performing SPE during GC or LC analysis of the preceding sample
  • More than 50% time saving for overall analysis, compared to manual processing

Following the SPE clean-up steps, the MPS can introduce the sample extract directly to an LC/MS or GC/MS system for analysis. As an alternative, the MPS WorkStation is used as a stand-alone sample preparation robot, preparing samples for multiple LC/MS or GC/MS systems in your laboratory.

The GERSTEL SPE enables automated sample preparation and analysis even for complex samples. Samples are prepared in a simple and safe manner combining accurate results with high throughput. The complete system is easily and efficiently controlled from the Agilent ChemStation software or from the GERSTEL MAESTRO software.
Sample preparation steps are selected by mouse-click from a simple pull-down menu and can easily be combined with automated SPE:

  • Dilution and standard addition
  • Automated weighing, centrifugation and sonication
  • Derivatization before or after SPE
  • Heated or cooled conditioning and mixing

Product Specifications

Uses Sample preparation and sample introduction system for automated Solid Phase Extractio (SPE) based on standard cartridges. Conditioning, extraction and elution is performed in a sealed system. An automated concentration can be selected for improved detection limits. SPE can be combined with introduction of the eluate to a GC or LC system or performed off-line for subsequent analysis of the SPE eluate using a separate GC/MS or LC/MS system.
