Abstract
An aerosol charge conditioner includes a source of ionizing radiation, an ionization region, and a conduit transporting an aerosol sample through the ionization region. The conduit is constructed and arranged to control irradiation of the aerosol sample. The conduit includes an inlet conduit communicatively connected to an outlet conduit. The inlet conduit has a first diameter and a distal end disposed in the ionization region. The outlet conduit has a second diameter which is greater than the first diameter of the inlet conduit and a proximal end disposed in the ionization region. A secondary gas supply is communicatively connected to the ionization region. A method for controlled ionization of aerosol particles using radiation as a source is also disclosed.
