An octupole radio frequency (rf) ion guide was evaluated for storage and filtering of ions generated by electrospray prior to introduction into an ion trap mass spectrometer. The control of the rf potential on the ion guide enabled its operation as a high-pass mass filter, removing low-mass chemical
