the impact of a single ion. A positive ion arrives at the mouth of the detector, it is deflected onto the first dynode, held at a high negative voltage. The impact of the ion releases several free electrons from the dynode surface, which are repelled from the high negative voltage at the front and strike the next dynode.

Ion Channels and the Electrical Properties of Membranes ...

Ion Channels Are Ion-Selective and Fluctuate Between Open and Closed States. Two important properties distinguish ion channels from simple aqueous pores. First, they show ion selectivity, permitting some inorganic ions to pass, but not others.This suggests that their pores must be narrow enough in places to force permeating ions into intimate contact with the walls of the …
