Abstract

Polycyclic aromatic hydrocarbons (PAHs) are hazardous due to their carcinogenic effects. Current monitoring relies on centralized labs, hindering efficient enforcement of regulations. This paper presents a hand-portable high-performance liquid chromatography (HPLC) system with a broadband spectral detector for on-site PAH analysis. The system accurately identifies all 24 tested PAHs, including the US EPA priority pollutants, using spectral absorption profiles, independent of retention times. Unsupervised methods effectively detect and classify co-eluting and hidden peaks, mitigating matrix effects. This portable platform enables sophisticated field measurements, facilitating real-time decision-making.
