Introduction
This Application Note describes the performance of a sorbent tube and optimised analytical protocol dedicated to the detection of ppt-level polycyclic aromatic hydrocarbons (PAHs) in ambient air. Using active (pumped) sampling with analysis by thermal desorption–gas chromatography (TD–GC), this innovative approach completely avoids the labour-intensive solvent-extraction protocol employed in many standardised methods.
