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 and into the HCD cell, an added multipole … Ver mais 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 … Ver mais In a triple quadrupole mass spectrometer there are three quadrupoles. 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 … Ver mais Homolytic fragmentation is bond dissociation where each of the fragments retains one of the originally-bonded electrons. Ver mais 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 fragment ions observed in low-energy CID is … Ver mais Ions trapped in the ICR cell can be excited by applying pulsed electric fields at their resonant frequency to increase their kinetic energy.
