High-Throughput Pressurized Fluid Extraction System

Pressurized Fluid Extraction (PFE), also known as Accelerated Solvent Extraction (ASE), Pressurized Solvent Extraction (PSE), or Pressurized Liquid Extraction (PLE), is a sample preparation technique used to extract organic compounds from solid and semi-solid samples.

The RayKol HPFE High-Throughput Pressurized Fluid Extraction System automates the extraction process through software-controlled operation, helping to shorten extraction time and reduce solvent consumption compared with conventional Soxhlet extraction.

The HPFE system can be used for the extraction of organic compounds, pesticides, and polychlorinated biphenyls (PCBs) from soil and sediment samples. It can also be combined with a parallel vacuum evaporation system for subsequent concentration of extracts, providing an integrated sample preparation workflow for soil and environmental analysis.

Compared with conventional Soxhlet extraction, RayKol states that the extraction time can be reduced from more than 10 hours to approximately 15–30 minutes, while solvent consumption can be reduced from approximately 200 mL to 20–50 mL.
