Gas-Phase Reactions of ClMn(H_2O)~+ with Polar and Nonpolar Hydrocarbons in a Mass Spectrometer

摘要

ClMn(H_2O)~+ efficiently ionizes various types of hydrocarbons, both polar and nonpolar, as well as other compounds typically present in petroleum, to exclusively form pseudomolecular ions (adduct-H_2O). Even highly branched hydrocarbons yield solely this product ion when exposed to ClMn(H_2O)~+. Collisional activation of these product ions yields structural information on the hydrocarbons and may allow distinction and identification of isomeric hydrocarbons.
