Extraction of organic compounds from complex matrices is commonly seen as a challenging problem in modern sample preparation. Analytes of insterest such as polycyclic aromatic hydrocarbon(PAH) and polychlorinated biphenyls(PCB) can easily be adsorbed to sample matrices, causing seperation failure using conventional liquid extraction. Besides, conventional liquid extraction methods such as Soxhlet extraction require large solvent consumption and long extraction time, consequently, low efficiency became a common issue to lab productivity.
Based on these above, RayKol HPFE 06's high-throughput pressurized fluid extraction system can raise the boiling point of solvents using high pressure. And with high temperature, solubility and diffusibility of target compounds are increased substantially, to reduce extraction time to 15 to 30 minutes from more than 10 hours and decrease solvent consumption to 20 to 50mL from 200mL, therefore boosting efficiency and lower extraction cost.
