Optimised Ion Mobility Separation Timescales for Targeted Ions

摘要

An analytical device for analysing ions is provided comprising a separator for separating ions according to a physico-chemical property and an interface comprising one or more ion guides. A quadrupole rod set mass filter is arranged downstream of the interface. A control system is arranged and adapted: (i) to transmit a first group of ions which emerges from the separator through the interface with a first transit time t1; and (ii) to transmit a second group of ions which subsequently emerges from the separator through the interface with a second different transit time t2.

1. An analytical device for analysing ions comprising:
a separator for separating ions according to a physico-chemical property; an interface comprising one or more ion guides, each ion guide comprising a plurality of electrodes; a quadrupole rod set mass or mass to charge ratio filter arranged downstream of said interface; and a control system arranged and adapted: (i) to transmit a first group of ions which emerges from said separator through said interface with a first transit time t1; and (ii) to transmit a second group of ions which subsequently emerges from said separator through said interface with a second different transit time t2.
