Multiply charged negative ions anions

EDD is a promising new FTICR technique, and is the negative ion complement to ECD. Both these electron-mediated techniques involve a radical ion intermediate, produced by either electron attachment to multiply charged cations (ECD) (Equations (48) and (49)) or electron removal from multiply charged anions (EDD) (Equation (50)). [Pg.354]

Sulfonated dyes were among the first compounds to illustrate the benefits of ESI-MS.The analysis of dyes by LC-MS is a seasoned field (reviewed, for example, by Yinon et al.and LC-MS is frequently used to analyze dyes, especially sulfonated azodyes.These anionic species can best be detected with ESI-MS in the negative ion mode. A common feature of polysulfonated dyes is the formation of multiply charged molecular anions with variable numbers of sodium. Adding di- or tri-alkylammonium cations to the eluent helps suppress the formation of... [Pg.363]
