ABSTRACT:
A sample introducing apparatus for an inductively coupled plasma mass spectrometer comprises a means supplying the inert gas for carrying the vaporized sample, a heater for defining the path through which the inert gas is passed as well as having the inner surface, on which the sample to be analyzed thereon is put and for generating the heat with the electrical being applied, in which the film structure is formed on said surface, and the surface contacted with the inert gas of the film structure vaporized the sample made of any one of the high melting metal oxide and the high melting metal nitride, an electrode structure for supporting the heater and supplying the electrical power to the heater.
