Claim 0:
1. A mass spectrometry system, comprising:
an ion source for generating ions;
an ion guide positioned downstream of the ion source;
an interface disposed between the ion source and the ion guide and having a plurality of states to modulate introduction of ions generated by the ion source into the ion guide as a plurality of ion pulses;
a mass analyzer disposed downstream of the ion guide; and
one or more controllers for switching the interface between the plurality of states,
wherein the one or more controllers are configured to switch the interface between the plurality of states to change a pressure in the ion guide so as to cause a separation of at least a portion of ions in each of the ion pulses according to m/z ratios thereof.
