Claim:
1. A coupling device for a mass spectrometry apparatus that is an interface member to be connected to an atmospheric-pressure real-time mass spectrometry apparatus, the coupling device comprising: (A) an excitation gas introducing port, a sample gas introducing port, and an ionized sample gas discharging port; (B) a channel through which the excitation gas introducing port and the ionized sample gas discharging port are in communication; (C) a space for mixing an excitation gas and a sample gas being formed in a region of a portion of the channel recited in (B), by the coupling device having a structure in which the sample gas introducing port and the channel recited in (B) are in communication; and (D) an outside air introducing port, and having a structure in which a channel from the outside air introducing port is in communication with the channel recited in (B).
