Automated Solvent Extraction System – EDGE

A simple solution to a complicated challenge.

Automates the technologies of PFE and dSPE.

The EDGE® is an automated extraction system that’s faster than Soxhlet, more automated than QuEChERS, and simpler than other solvent extraction systems. Extract a wide range of samples and sizes at least 3 times faster than other pressurized fluid extractors. This includes filtering, cooling, and washing. The EDGE has revolutionized the extraction process for sample preparation.


  • Fastest technique available
  • Sample holders are easily assembled and cleaned (Q-Cups)
  • Small footprint
  • One technology with unlimited applications

Automated Extraction Process

Touch “start” to begin the automated process.

1. Select a Method

After a rack of Q-Cups containing samples are loaded into the EDGE, simply select the proper method, program the number of samples, and hit “Start”.

2. Autosampler Loads Sample

The Q-Cup is automatically loaded into the chamber by the autosampler. The pressure cap then creates a pressurized seal on the top of the Q-Cup.

3. Matrix is Extracted

Solvent is first added through the bottom to fill the gap between the chamber and Q-Cup, this aids in heat transfer. Then, solvent is added through the top of the Q-Cup to wet the sample.

As the chamber walls are heated, the pressure in the gap increases. This overcomes the pressure inside the Q-Cup, forcing the solvent to disperse into the sample.

4. Extract is Collected

Once the sample reaches temperature, the solvent is dispended through the Q-Disc, the cooling coil, and into a collection vial.
