摘要：

A modification to the electronics controlling the collision energy of an RF‐only quadrupole collision cell in a BEqQ geometry mass spectrometer is described. The modification allows the collision energy to be ramped from 0–500 eV while scanning the quadrupole mass analyser. The collision‐induced dissociation spectra generated using a ramped collision energy exhibit a 10%–100% increase in product‐ion abundance. Copyright © 1990 John Wiley & Sons Limited
