Automated Extraction System (AES) – Oil in Water

The Automated Extraction System (AES) combines the PX2 Photometer with a programmable sampling system capable of performing fully automated liquid-liquid extractions and delivering the extract to an analysis cell.

First, the AES retrieves a known volume of sample from a process stream via fast loop and adds a known volume of solvent.  Next, it mixes the sample and solvent phases to create an emulsion, which allows the solute to transfer to the solvent phase.  Finally, the AES instrument determines the concentration of the solute by means a fluorescence measurement made in the analysis chamber.

The AES contains all of the hardware to perform the mechanical functions of the extraction, and is designed to be mounted near the process line at which the measurement will be performed.

The Auto-Tune feature takes the guesswork out of selecting the optimal measurement settings, and the Auto-Calibrate function only requires the user to prepare one standard.
