Scott-type spray chamber
The aerosol enters the inner compartment and is forced to change direction 180°, returning through the outer compartment, where it exits the spray chamber and is directed to the plasma. An external drain is provided to remove condensed solvent.
For some specialized applications a water jacket or an electrical Peltier cooler is provided that acts as a thermostat for the spray chamber. By lowering the temperature, the vapor pressure of the solvent can be significantly reduced. This results in a substantial reduction in molecular oxide (in the case of water as the solvent) formation and potentially interfering peaks in the background spectrum of the plasma originating from solvent species. Many variations of this type of spray chamber are available.
