WebAbstract Collision-induced dissociation of 0.65 to 3.2 keV CO/sup +/ has been examined in an apparatus with an extended flight path through which reactant ions take a long time to travel. Reactant ions were produced by electron impact ionization and the short-lived excited states decayed radiatively prior to ion--molecule interactions. WebCollision-Induced Dissociation: direct, Fast Quantification of Complex Substances. A major challenge of online mass spectrometry is the quantification of measured compounds (the determination of sensitivity). Often, dozens to hundreds of compounds are measured, and calibration of each with a cylinder or other calibration system is far too time ...
WebJan 15, 1994 · The U.S. Department of Energy's Office of Scientific and Technical Information Collision-induced dissociation (CID), also known as collisionally activated dissociation (CAD), is a mass spectrometry technique to induce fragmentation of selected ions in the gas phase. The selected ions (typically molecular ions or protonated molecules) are usually accelerated by applying an electrical … See more Low-energy CID is typically carried out with ion kinetic energies less than approximately 1 kiloelectron volt (1 keV). Low-energy CID is highly efficient in fragmenting the selected precursor ions, but the type of … See more Ions trapped in the ICR cell can be excited by applying pulsed electric fields at their resonant frequency to increase their kinetic energy. The … See more Homolytic fragmentation is bond dissociation where each of the fragments retains one of the originally-bonded electrons.

The first quadrupole termed "Q1" can act as a mass filter and transmits a selected ion and accelerates it towards "Q2" which is termed a collision cell. The pressure in Q2 is higher and the … See more Higher-energy C-trap dissociation (HCD) is a CID technique specific to the orbitrap mass spectrometer in which fragmentation takes place external to the trap. HCD was formerly known as higher-energy C-trap dissociation. In HCD, the ions pass through the C-trap … See more
WebBoth LysNTA and AspIDA spontaneously form ternary complexes with GaIII and phosphorylated amino acids and phosphopeptides upon mixing in solution. Collision-induced dissociation of positive complex ions produced by electrospray produces common fragments (LysNTA + H)+ or (AspIDA + H)+ at m/z 263 and 205, respectively.
