Residual Gas Analysers

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, semi-conductor, 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

Application Overview

• Vacuum Furnaces
• Semi-Conductor Processes

• Research and Development
• Vacuum Process
• Integration with existing vacuum systems

RGA Software

PAS-Scan software included

ProtaR is supplied with free PAS-Scan software for RGA peak analysis. This simple to use software allows for Analogue, Histogram, Trend and Leak scans to be taken quickly and simply. Scans can be carried out a signle mass (leak detection), specific masses (mass jumping) or as a full analogue scan over the mass range of the RGA. The mass spectra can be plotted on linear or logarithmic scales.

Individual RGA settings can be saved to the electronics of the RGA or can be saved to an .xml file. This allows a single network PC to connect to multiple RGA with different settings. Replacement electronics can be provided to give redundancy and coverage across multiple RGA installations.
