Structural CharacterizationLTQ XL

Collision Induced Dissociation (CID)

  • Resonance excitation of precursor at low q; low energy collisions with He
  • Universal, no tuning required, high efficiency
  • Low mass cutoff

Pulsed “q” Dissociation (PQD)

  • Short resonant excitation of precursor at high q, rapid shift to very low q, high energy collisions with He
  • Selective, no low mass cutoff, low noise
  • Tuning required, low efficiency

Higher Energy Collision Induced Dissociation (HCD)

  • Acceleration of ion packet through N2 cell, high energy collisions with N2
  • High efficiency, no low mass cutoff
  • Tuning required
Not Available
