Power-Prep PLE™ System
Power-Prep/PLE ™ is a high speed Pressurized Liquid Extraction system for Dioxins, PCBs, Pesticides, PAHs and BFRs analysis. With the Power-Prep/PLE™, one just needs to load solid or liquid samples into the PLE cartridges, and press the start key. The entire extraction are performed automatically and unattended producing excellent precision and high recoveries.
This system uses low cost Disposable filtration as well as disposable stainless steel extraction Cartridges. This feature allows samples containing ppq to >ppb target analytes be extracted on the same unit.
Parallel sample processing, real time plotting of Temperature & pressure, trouble free operation as well as economical pricing Make Power-Prep/PLE the system of choice for environmental labs.
The following samples can be deposited directly to Power-Prep/PLE™ cartridges:
Meat, fish, cheese, soil, serum


PRINCIPLES OF OPERATION：
The PLE™ (Pressurized Liquid extraction) works similar to Soxhlet extraction, with the exception that during the extraction process the solvents inside the PLE™ extraction cartridge are near their supercritical region which has high extraction properties. In the physical region the high temperature makes possible the high solubility and high diffusion rate While the high pressure keeps the solvent below its boiling point. At high pressure and high temperatures the solvents penetrate the solid samples at a much higher rate permitting a fast and efficient extraction process with minimal solvent usage.
To operate the PLE™, 5 to 100 grams of the sample is mixed with sodium sulfate, loaded in the extraction cartridge and capped with two disposable filtration end fittings. The extraction cartridges are clamped inside the unique and easy to use PLE™ cartridge seal cups. Upon pressing the start key, the HPLC pump dispenses the organic solvent of choice, such as Hexane, DCM, Toluene, etc., into the extraction cartridges. The PLE™ control system then starts the pressurization and heating of the samples. The pressure is maintained at 1500-3000 PSI, at temperature 70-200 C degrees. depending on the method. The extracted solvent containing target analytes is then transferred to the Power-Prep for column clean up or collected in collection vessels.
