Lenses or No Lenses? A Study of Ion Transfer Efficiency at Interfaces in a Lens-Free Triple Quadrupole MS

The efficiency of ion transfer between the quadrupole mass analyzers and the Q2 collision cell in a triple quadrupole mass spectrometry (MS) is critical for instrument robustness and sensitivity. Q2 is a radio frequency (RF) only non-mass filtering quadrupole containing only an inert collision gas such as Ar, He, or N2 to provide collision induced dissociation of the precursor ion selected in Q1.
