linear ion trap造句

The first ETD experiments at the University of Virginia utilized a radio frequency quadrupole linear ion trap ( LQT ) modified with a chemical ionization ( CI ) source at the back side of the instrument ( see diagram at right ).
Later a lab at the University of Wisconsin adapted a hybrid quadrupole linear ion trap-orbitrap mass spectrometer to use ETD . This method also used a front-end ionization method for the radical anions of 9-anthracenecarboxylic acid via pulsed dual ESI sources.
Electron-transfer and higher-energy collision dissociation ( EThcD ) is a combination ETD and HCD where the peptide precursor is initially subjected to an ion / ion reaction with fluoranthene anions in a linear ion trap, which generates c-and z-ions.
