Fully Automated, Trace-Level Determination of Parent and Alkylated PAHs in Environmental Waters by Online SPE-LC-APPI-MS/MS

Instrument Type: LCMSMS

Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants produced by both human activities and natural phenomena. PAHs enter surface waters mainly by atmospheric fallout, urban runoff, municipal and industrial effluents, and the spill or leakage of petroleum and its derivates. We developed a fast, fully automated protocol for determining a large number of parent PAHs and alkylated PAHs in environmental waters, using online solid–phase extraction coupled with liquid chromatography and tandem mass spectrometry.
