Abstract: A deposit-reducing ionization source for sample introduction to a mass spectrometer is provided. It comprises a heated vessel with a set of circulating hot gases to avoid any condensation to be formed within the volume of the vessel, keeping the vessel clean. The vessel has a tubular cross section with a conduit attached to its side wall. The vessel is placed in front of the orifice of a curtain cone. An exhaust port is on the opposite side of the conduit on the wall and close to the curtain cone. A nebulizer is placed inside the conduit. A nebulizing gas and an auxiliary gas are introduced in the conduit and a curtain gas is introduced in the curtain cone.
