    摘要: An analytical apparatus provides for the separation and analysis of a subset of ions from a mixture of ions in a gas. The apparatus includes an ion supply, such as an electrospray, which provides a population of variously charged ions. An analyzing chamber is coupled to the ion supply and includes a first wall with an inlet orifice for receiving the flow of variously charged ions, and a second wall opposed to the first wall. A laminar gas flow is established within the analyzing chamber along a flow axis. The second wall is provided with an outlet orifice that is displaced by a determined distance along the gas flow axis from the inlet orifice. A potential difference is applied between the first and second walls which causes the flow of ions, introduced via the inlet orifice, to migrate towards the outlet orifice. The laminar gas flow displaces ion flight trajectories along the flow axis, so that only the ions with a mobility near a specific value reach the second wall close enough to the outlet orifice to be sampled through it. The outlet orifice is coupled to the inlet of a mass spectrometer to enable analysis of the ions emerging from the outlet orifice.
