ABSTRACT:
An analysis system includes induction coupled plasma apparatus into which sample material to be analyzed is introduced for excitation in the plasma, optical measuring apparatus coupled to the induction coupled plasma apparatus for analyzing the sample material, and mass spectrometer apparatus also coupled to the induction coupled plasma apparatus for analyzing the sample material. The mass spectrometer apparatus includes structure defining a first region, a sampling member adjacent the induction coupled plasma apparatus that has an orifice through which at least some ions characteristic of the sample material may pass into the first region, structure defining a second region, and a gate valve between the first and second regions. The gate valve is open when the analysis system is operating in mass spectrometer mode, and is closed when the system is operating only in optical measuring mode. Inert gas is flowed outwardly through the sampling member orifice towards the induction coupled plasma apparatus from the first region of the mass spectrometer when the analysis system is operating in the optical measuring mode.
