Ion/Ion Reactions in Ion Storage Devices
- 總結
- Purdue University researchers have developed a technology which allows for the mutual presence of positively charged and negatively charged ions such that the ions can react with one another and whereby the kinetics of reaction of ions of selected mass-to-charge ratios can be reduced relative to those of nonselected ions. This capability allows for highly charged ions derived from a particular high mass molecule, usually formed via electrospray ionization, to be accumulated into a selected charge state. Furthermore, this capability allows for ions present in a complex mixture of ions of like polarity to be selectively removed from the population of ions undergoing ion/ion reactions. This capability is particularly useful for the analysis of complex mixtures of high mass molecules.
- 技術優勢
- Provides means for accumulating ions into predetermined charge states for isolating species from complex mixtures of ionsIsolates one or more ions of defined mass-to-charge ratio(s) Minimizes the extent to which the isolated ions undergo ion/ion reactions in the presence of ions of opposite polarity

- *Abstract
-
- *Background
- Ion/ion reaction technologies that are used to manipulate ion charge state distributions in mass spectrometers have been limited to product ion distributions that are determined solely by the kinetics of reaction. This limitation of product ion distributions results in the inability to accumulate ions in an arbitrary charge state while ions are undergoing ion/ion reactions.
