Talking of charge carrier drift, you may be interested in this cocaine sniffer.

Wouldn't it be interesting to apply a transverse magnetic field to this
transit time spectrometer,
in order to sort for doubly and trebly charged fragments, a la MS?
It would need only a comb electrode besides the field.
