Automated extraction system for PFAS analysis
The EDGE PFAS is an automated extraction system that exists for the preparation of solid and semi-solid samples for PFAS analysis. The system performs the complete extraction workflow, including extraction, filtration, cooling, and washing, faster than traditional PFAS solvent extraction methods.
The system exists without PFAS-containing materials in components that come into contact with the sample, helping laboratories perform PFAS extractions without concerns about background contamination. The EDGE PFAS also meets the performance criteria of EPA Method 1633.
Automated PFAS extraction workflow
The EDGE PFAS automates multiple steps of the sample preparation process. Place the sample in the Q-Cup, select the appropriate method, and start the extraction using the integrated touchscreen.
The system automatically adds the solvent, performs the extraction, filters the extract, cools the sample, and completes an extensive washing step before loading the next sample. Once the extraction is complete, the extract can be taken directly for analysis.
The system supports both pre-programmed One Touch methods and user-defined methods, allowing laboratories to select the workflow that best suits their application.
It is possible to program up to 12 samples for automated processing, allowing laboratory staff to perform other tasks while the system completes the extraction sequence.
PFAS-free sample pathway
The EDGE PFAS is designed to minimize the risk of PFAS background contamination during sample preparation. Polypropylene tubing, centrifuge tubes, and a side enclosure provide a PFAS-free environment for sample handling.
In addition, the Q-Cups and Q-Discs have been tested to be PFAS-free, while all components that come into contact with the sample are tested to ensure they do not contain PFAS.
eCleanUP for PFAS sample preparation
The EDGE PFAS can be used with eCleanUP, a sorbent that has been tested to be free of PFAS.
During the extraction process, eCleanUP helps remove both water and impurities from the extraction mixture. For optimal results, it is added together with the sample before extraction.
Sample compatibility
The EDGE PFAS is suitable for a wide range of sample types, including:
- Environmental samples
- Food samples
- Consumer products
- Cosmetics
Regardless of the sample type, the system produces a particle-free extract collected in a PFAS-free centrifuge tube, ready for analysis.
Simplified PFAS sample preparation
By automating solvent addition, extraction, filtration, cooling, and washing within a single workflow, the EDGE PFAS reduces manual handling throughout the sample preparation process. The automated workflow helps reduce operator error, minimizes potential contamination sources, and allows laboratory personnel to spend less time on routine extraction procedures.
The EDGE PFAS combines automated extraction, PFAS-free sample contact materials, and support for EPA Method 1633 workflows to provide efficient and reliable PFAS sample preparation for solid and semi-solid samples.
Q-Cup Sample Holder
A simple solution to a complicated problem
The aluminum Q-Cup sample holder consists of three easy-to-assemble pieces.
Automated PFAS extraction process
Touch “start” to begin the automated process
- Select a method
Load a rack of Q-cups containing samples into the EDGE. Then, select the proper method, program the number of samples, and press “Start”. - Autosampler loads sample
The autosampler automatically loads the Q-Cup into the chamber, sealing it with the pressure cap. - Matrix is extracted
Solvent is added through the top of the Q-Cup to wet the sample. As the chamber walls heat up, the increased pressure forces the solvent into the sample. - Extract is collected
Once the sample reaches temperature, the solvent filters through the Q-Disc, passes through the cooling coil, and into a collection vial.
