Claim 14:
15. The method of claim 14, comprising:
applying a first voltage signal to the separation path;
generating, by the separation path, a first traveling drive potential based on the first voltage signal, the first traveling drive potential separating the first plurality of ions based on mobility of the ions;
operating the pre-filter switch in a first mode of operation;
transferring, by the pre-filter switch operating in the first mode of operation, the first group of ions entering the pre-filter switch from the separation path to the accumulation region,
operating the pre-filter switch in a second mode of operation; and
transferring, by the pre-filter switch operating in the second mode of operation, the second group of ions entering the pre-filter switch from the separation path to a discard region.
