This Application Note describes analysis of ppt-level PAHs in ambient air, using pumped sampling, thermal desorption, and gas chromatography. Using optimised sorbent sampling tubes, the method offers greater sensitivity compared to labour-intensive solvent-extraction protocols employed in many standardised methods.
