The mass range of mass spectrometers has been extended by almost an order of magnitude in the past decade, ionization procedures have been introduced which allow ionic, nonvolatile compounds to be examined, and new capabilities have been achieved through the successful integration of separation and analysis techniques. In combination with other techniques,(More)
analyte penetration into the porous silicon is important. The energy for analyte release from the surface may be transferred from silicon to the trapped analyte through vibrational pathways or as a result of the rapid heating of porous silicon producing H 2 (ref. 26) that releases the analyte. Alternatively, as porous silicon absorbs hydrocarbons from air(More)
Polychlorinated 2-phenoxyphenols were studied by negative ion mass spectrometry. Common to almost all of the methane enhanced negative ion mass spectra were (M-1)-, (M-36-)-., (M-37)-, (M-72)-., and chorinated quinoxide ions. The (M-36)-. ion does not apparently form in a mechanism analogous to the thermal or photochemical ring closure of these compounds to(More)
