摘要:
The compensation potentials on the compensation electrodes of an ICR measuring cell are sequentially adjusted so that an ICR measurement with the longest possible usable image current transient is produced. Then, subsequent ICR measurements are made using the ICR cell with the optimally adjusted compensation potentials. Depending on the kind of ion mixture involved, measurements with image current transients from 10 to more than 20 seconds long can be performed, from which mass spectra with a maximum mass resolution without peak coalescence can be obtained.
