Abstract
An ion source is formed by a chamber. A capillary tubeforms an inlet to the chamber. A heateris associated with the capillary tube to heat air drawn into the chamber. An electrodeis provided in the chamber and maintained at a voltage in the range 100 to 500 volts. In use the source is connected to an analyzer such as a mass spectrometer. The capillary tube is open to the atmosphere. Pressure in the chamber is reduced, and pressure in the analyzer is further reduced. An electrical potential is applied to the electrode to create a discharge within the chamber. Ionization of air molecules within the chamber leads to ionization of any sample molecules present in the chamber. Ions are swept into the analyzer for analysis.
