The 'farad' should not be confused with the faraday, which is the electric charge carried by one mole of singly charged ions.
However hydrogen also forms singly charged clusters (H) with n up to 120.
As the singly charged particles pass through the plasma, they are further ionized creating the doubly charged secondary beam.
Secondly, a neutralizer isn't needed, since there are equal numbers of electrons and (singly charged) positive ions emitted.
The main factor affecting rates is charge: highly charged metal aquo cations exchange their water more slowly than singly charged species.
Thus, histamine is normally protonated to a singly charged cation.
The positive ions are mostly singly charged.
This is equivalent to saying that they can exist in three charged states, the doubly charged, the singly charged, and the neutral.
The singly charged state had to wait till 2001 by the time they had collected more data.
For simplicity I have written only singly charged cations and anions and have considered only one source of buffering salt.
