Screening of polycyclic aromatic hydrocarbons in soil by on-line fiber-optic-interfaced supercritical fluid extraction spectrofluorometry


Screening of polycyclic aromatic hydrocarbons in soil by on-line fiber-optic-interfaced supercritical fluid extraction spectrofluorometry



Analytical Chemistry 68(14): 2386-2391



ISSN/ISBN: 0003-2700

DOI: 10.1021/ac960038n

An interface for spectrofluorometric measurements in the supercritical (SC) CO2 emerging from the extraction cell of a SC fluid extractor prior to de-pressurization was developed. The combined system allowed real-time on-line fluorometric monitoring of the supercritical fluid extraction (SFE) process and provided qualitative and semi-qualitative information from SC extracts of real and spiked samples.
