SFE of airborne particulate matters as preparation for HPLC analysis of benzo(a)pyrene

Among 234 airborne pollutants the polycyclic aromatic hydrocarbon benzo-(a)-pyrene has been assigned as one of the priotrity pollutants by Central Environment Council, Ministry of the Environment, Japan. This material is reported to have carcinogenic and other adverse health effects and the monitoring has been conducted to determine its origins.

The conventional measurement method requires time-consuming Soxhlet extraction of collected particulate matters using benzene and other hazardous organic solvents. Jasco has investigated the applicability of Supercritical Fluid Extraction of benzo(a)pyrene in airborne particulate matters using carbon dioxide as a sample preparation method for HPLC analysis.
