The source exhaust is a solvent collection box where atomized solvent and sample collect and condense. The exhaust collects the parts of the sample that are not ionized and transferred to the analyzer region.
A Teflon sleeved tube draws the condensed solvents from the bottom of the exhaust block by a vacuum differential through a venturi block. The venturi operates by principle of a high volume gas passing by a smaller orifice creating a negative pressure. This negative pressure draws the solvent (vapor and condensate) into the high volume gas, and then to a waste vessel.
Solvents used in a typical analysis may be hazardous if breathed in an open atmosphere. For this reason, the waste vessel is a closed system with the inlet tube from the mass spectrometer, and an outlet tube to a negative flow environmental exhaust that meets local governmental requirements. The critical components of the source exhaust that can cause problems are the venturi gas supply, the venturi outlet/waste, and the line to the waste vessel. These conditions can lead to a blocked venturi, or a flooded exhaust drain.
