• Water vapor effect in spectrochemical analysis using 2450 MHz discharge was investigated. The discharge was generated by flowing Ar gas as a discharge forming and carrier gas. In the use of UHF Plasma Spectra Span in this experiment, about 11mg/<I>l</I> water vapor is contained in the discharge forming gas under the specified condition of the desolvation device. A temperature change of the cooling water of the desolvation device, from 15°C to 0°C, makes the amount of the water vapor in the aerosol decrease to one half. In this case, the spectrum intensity of Sr II 407.7nm line increased to a maximum. At a lower temperature of the cooling device using dry ice, the intensity of the above spectrum line rather decreased, and the discharge became unstable.
