An inductive RF discharge in water vapor for atomic-emission spectrometry

Abstract

The paper presents the results of experimental measurements of the emission properties of water inductively coupled plasma. The plasma temperature is calculated using the Boltzmann method. It is shown that the temperature decreases with increasing pressure. The plasma resistance, its conductivity, and the thickness of the skin layer are estimated. Analysis shows that the emissivity of water plasma can be optimized while maintaining the power consumption.
