Two ions in one trap: ultra-high precision mass spectrometry?

By simultaneously trapping two different ions in a Penning trap, we compared their cyclotron frequencies (whose ratio gives their atomic mass ratio) with a precision of about 10/sup -11/ in only a few hours. Unfortunately we observed large abrupt changes in the ratio for which we do not have an explanation.
