<p>A mass spectrometer is provided comprising a first ion trap arranged upstream of an analytical second ion trap. The charge capacity of the first ion trap is set at a value such that if all the ions stored within the first ion trap up to the charge capacity limit of the first ion trap are then transferred to the second ion trap, then the analytical performance of the second ion trap is not substantially degraded due to space charge effects.</p> |
