Abstract:
1. An ionization source useful with an atmospheric pressure mass spectrometer comprising: a source capable of ionizing either liquid or gaseous effluent from a preceding separation apparatus and of introducing the ions from an atmospheric pressure region of the mass spectrometer into a vacuum region of the mass spectrometer for mass analysis of the ions, the source including: an ionization arrangement, an enclosure for enclosing the ionization arrangement thereby defining an ionization region, an interface for facilitating the transport of chemical components from either a source of liquid effluent or a source of gaseous effluent into the atmospheric pressure region, the interface comprising a tubular member, made of a high temperature tolerant material, having an exit end and an entrance end, the interior of the tubular member being able to be heated to produce a uniform temperature throughout the interior of the tubular member.
