ABSTRACT:
An ionization device for ionizing a liquid sample may be disposed between a liquid chromatograph and an atmospheric pressure ionization mass spectrometer. A gas inspirator supplies a mixed nebulizing gas, and a nebulizer includes a nozzle for spouting an effluent from the liquid chromatograph so as to supply an ionized particle of the effluent to the atmospheric pressure ionization mass spectrometer. The inspirator has a taper passage therein which is formed to be gradually narrower from one side for taking in the nebulizing gas to the other side for taking out the mixed nebulizing gas. The taper construction is provided with a port for providing the auxiliary gas thereon in order to obtain a constant mixing ratio of the auxiliary gas to the nebulizing gas.
