The UGA and UGA LT Series Universal Gas Analyzers
are state-of-the-art bench top mass spectrometers that
operate from above atmospheric pressure to UHV. They are
ideal for on-line monitoring and analysis of gas mixtures.
Whether you’re measuring trace-level contaminants, solvents,
hydrocarbons, refrigerants or corrosive gases, your UGA
analyzer is up to the task.
UGA applications include semiconductor exhaust gas
monitoring, glove box analysis, fuel cell studies, Freon
detection, pollution monitoring, fermentation studies and
general R&D vacuum analysis.
These analyzers are also simple to operate and maintain. The
chassis design allows the instrument to be operated vertically
or horizontally, and both front-panel and computer operation
are supported. The UGA LT series is a simplified design for
less demanding applications.
Principle of Operation
The UGA system uses a two-stage pressure reducing inlet to
sample gases at atmospheric pressure. After the pressure is
reduced to around 10–6 Torr, the gas stream is sent to a mass
spectrometer (residual gas analyzer — RGA) which measures
the concentration of each mass of interest.
The UGA Windows software provides a graphical user
interface for complex graphing and data analysis. The
software also allows remote control of the system’s valves,
heaters and pumps.
