Abstract
A method based on gel permeation chromatography as sample clean-up followed by HPLC - fluorescence - UV is successfully developed for measuring the contents of 16 PAHs in airborne particulate after Soxhlet extraction of the samples. The clean-up process is proved to be efficient by the analysis of SRM from NIST. The HPLC is operated at gradient steps with constant flow followed by UV and optimized multi-step fluorescence detection. A complete run of HPLC requires less than 30 minutes with satisfactory resolution. The detection limits obtained with UV detection ranged from 0.017 to 2.542 ng/m3, and those of fluorescence are from 0.001 to 0.044 ng/m3. Precision of measurement is within 9.0%. This method is applied to monitor the PAH contents is the airborne particulate samples collected in Taipei city at ten different sampling sites with particle size distribution measurements.
