✦ Synopsis

A simple flow cell membrane inlet for Volatile Organic Compounds (VOCs) was constructed and tested in our laboratory. The purpose of this study was to evaluate the performances of the Membrane Inlet-Quadrupole Mass Spectrometry technique for on-line analysis and continuous monitoring of various compounds from environmental samples. The method showed a good linearity, precision, and reproductibility for some frequently used chemical solvents such as benzene, toluene, acetone, methanol, and ethanol. The method permits the determination of concentrations down to 0.04-4 mg m -3 , depending on the compounds.

Open-loop stripping analysis (OLSA) was evaluated for the determination of volatile organic compounds that are often found as contaminants in drinking w ter produced offshore. The recoveries of alkylbenzenes, halogenated "( hydrocarbons, alkanes and some polar compounds were, in addition to their ph
