Abstract
The invention comprises apparatus for use with atmospheric pressure ionization sources in which an aerosol is formed from a solution of a sample. The aerosol is received in a hollow member and discharged outside the chamber of the ionization source in order to reduce contamination of the ionization source itself by involatile material in the solution and by previously analysed samples. The hollow member is easily removable from the ionization source to facilitate cleaning and replacement. Ionization sources, mass spectrometers, and ion mobility spectrometers comprising the apparatus are also described.
