SFE – SFC Fusion Technology ultimate in productivity
SFE – SFC Fusion Technology is an extraction- separation-isolation technique that combines the performance of CO2 extraction and CO2 separation techniques in one step.
The in-line extraction-injection technique (X-injection) is available for our standard SFE units. Dual SFE -SFC model extends the capabilities of the PIC Solution SFC units by enabling both extraction and separation with the same unit.

Extraction injection (X-injection) Technique
Requires PIC-Lab ExtractIon column
The Extraction-Injection technique (X-Injection, SFE -SFC) developed by PIC Solution is available for our semi-preparative and preparative systems.
It supports you in the purification of difficult-to-separate samples, the faster isolation of minor impurities and the separation of sensitive compounds.
The extraction-injection technique uses an extractor to dissolve the dry sample or biomass in the supercritical fluid before injection into the stationary phase.
Our SFE-SFC Fusion process technology is compatible with stacked injections and results in reproducible separations with excellent peak shapes. The amount of sample injected can be adjusted by changing the time, temperature and pressure of the extraction.
Since the sample is dissolved in the mobile phase, the possibility of sample precipitation is eliminated.
Procedure method for SFE -SFC separation
X-injection procedure
- fill extractor with biomass/substance
- install extractor in the chromatograph
- test your method
- produce the target substance

Our “One Machine/Device – Multiple Applications” strategy is designed to simplify processes and reduce costs.
The PIC Solution UEFC instruments can either be used for separation on a stationary phase or switched to an extraction process.
To enable standard extraction, an appropriately sized extraction vessel is connected to the UEFC units and the extraction steps are activated using our proprietary technology and software.
