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. The duration and amplitude of the pulse determines the ion kinetic energy. Because a collision gas present at low pressure … Ver mais • Electron-capture dissociation (ECD) • Electron-transfer dissociation (ETD) • Infrared multiphoton dissociation (IRMPD) Ver mais Web1 de nov. de 2024 · High-resolution CID and HCD spectra were collected at increasing collisional energy for each peptide in both the positive ion mode and the negative ion mode. We aim to verify previously observed CID behaviors of deprotonated peptides using this collection which included 33 peptides of 4–16 aa. Web11 de abr. de 2024 · The energies of higher energy collisional dissociation (HCD) were 20, 40, and 60 eV, and the average MS/MS spectrum was obtained.
