AEROSOL COLLECTION SYSTEM AND APPARATUS AND METHOD FOR ANALYZING POLYNUCLEAR AROMATIC HYDROCARBON USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide an improved aerosol collection system and provide an apparatus and a method capable of measuring PAHs in the atmosphere with high temporal resolution. PSOLUTION: A plurality of fine holes are formed in the surface of a collecting plate of the aerosol collection system. Aerosol particles on the collecting plate of the aerosol collection system are rinsed off by a solvent and recovered to a container. Ultrasonic waves are applied to the solution recovered to the container to extract a PAHs solution from the inside of the aerosol. Water is added to the extracted PAHs solution having a small polarity to increase its polarity. The PAHs solution is concentrated by a concentration column. The concentrated PAHs solution is analyzed by a high-performance liquid chromatograph attached with a fluorescence detector or a mass detector in the apparatus and the method for analyzing polynuclear aromatic hydrocarbon.
