SPE cleanup automated

Time saving – and highly precise

Solid Phase Extraction (SPE) may be time consuming and difficult-to operate, but if (SPE) is automated by integrating with GERSTEL MPs and Maestro, it becomes a much more efficient and reproducible process.

The GERSTEL MultiPurpose Sampler (MPS) with SPE works with standard cartridges. This 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
  • System may run on-line and just-in-time, minimizing variations due to degradation of sensitive samples, evaporation etc. This will improve RSD
  • More than 50 percent time saving for overall analysis, compared to manual processing

Automated SPE

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.

In addition to the automated SPE, other sample preparation steps are easily selected in a combined method, examples are:

  • Dilution and standard addition
  • Automated weighing, centrifugation and sonication
  • Derivatization before or after solid phase extraction
  • Heated or cooled conditioning and mixing
  • Solvent exchange

One method and one sequence table control the complete system including sample preparation and GC/MS or LC/MS analysis.
