Ionization chamber for atmospheric pressure ionization mass spectrometry

摘要

The ionization chamber consists of a plurality of ports to accept multiple identical devices or varying devices. Ports may be arranged at various positions on the ionization chamber and at various angles with respect to the sampling orifice leading into the vacuum chamber of the mass spectrometer. A plurality of sprayers may operate in a time modulated manner and thereby the simultaneous multiplexed analysis of a multitude of samples is facilitated.
