A spray of solvent is heated to relatively high temperatures (above 400 degrees Celsius), sprayed with high flow rates of nitrogen for desolvation and the entire aerosol cloud is subjected to UV radiation to create ions.
A spray of solvent is heated to relatively high temperatures (above 400 degrees Celsius), sprayed with high flow rates of nitrogen and the entire aerosol cloud is subjected to a corona discharge that creates ions. The resulting aerosol cloud is subjected to UV radiation to create ions.
