We report the first demonstration of the real‐time detection of metal‐containing compounds using membrane introduction ion trap mass spectrometry. Ferrocene and molybdenum hexacarbonyl vapors were detected in air using a composite membrane for sample introduction. The membrane consists of a plasma‐deposited polydimethylsilicone layer on a hollow microporous polypropylene fiber. The organometallic molecular ions were readily detected using charge exchange ionization employing oxygen from air as the reagent gas. When electron ionization was used, the expected greater fragmentation was seen in the mass spectrum. © 1997 John Wiley & Sons, Ltd.
