DEVELOPMENT AND OPTIMIZATION OF A MEMBRANE-INLET-PHOTOIONIZATION MASS SPECTROMETER FOR REAL-TIME ANALYSIS OF (POLY)AROMATIC COMPOUNDS IN AQUATIC SYSTEMS

摘要

Fast and sensitive analysis of (poly)aromatic hydrocarbons (PAH) is of high importance due to their impact on human health and the environment. However, very low concentrations of PAHs in marine environments complicate their detection and monitoring. A promising approach, regarding to direct determination of PAHs in marine systems, is resonance-enhanced multiphoton ionization (REMPI) coupled to membrane introduction mass spectrometry (MIMS).
