Residual Gas Analysers In The Spotlight

1st March 2023

For both research and industrial applications, Protea’s Residual Gas Analyser (RGA) products can be supplied in 100amu, 200amu and 300amu versions with smallest size and highest performance on the market.

The ProtaR Residual Gas Analyser (RGA) from Protea represents the smallest footprint electronics and maximum performance for value of any RGA on the market. Protea’s ProtaR RGA is a compact, stable and robustly designed Quadrupole Mass Spectrometer (QMS) instrument incorporating all the latest Quadrupole technology. ProtaR is a useful analytical tool for testing and residual gas analysis in leak testing, semiconductor, coating and process applications, being able to detect and measure almost all gases with low detection limits and fast response.

A mass spectrometer measures the mass-to-charge ratio of the molecules in a sample and by collecting and analysing the mass spectrum we can identify and quantify which molecules are present. The QMS within ProtaR contains a mass filter that is made up of 4 parallel circular rods, hence the name quadrupole.

• Very quick (millisecond) response time
• Detects almost any gas
• Low maintenance costs, with corrosion resistance inlets
• Advanced chemometrics for multi-gas quantification

Applications include Vacuum Furnaces, Semiconductor Processes, Metallurgy, Research and Development, Vacuum Process and Integration with existing vacuum systems.
