Abstract: Disclosed is a gas separation arrangement for separating and containing various types of gas from a collection chamber based on their different atomic masses. The chamber is connected to an ion diverter via a valve that when open permits the various types of gas to migrate from the collection chamber to an ionizer where the gas is ionized.

The trajectory of the ions is based on the mass of the ions, which separates the ions. Multiple collectors are positioned at different locations on an exit side of the ion deflector to receive the different ions traveling along their respective trajectories.
