Gas analysers for industry and research

We offer a full range of gas analysers, covering a huge variety of applications.

  • Residual gas analysers, for vacuum characterisation, vacuum leak detection, vacuum quality, outgassing studies, vacuum monitoring, thermal decomposition
  • Process gas analysers, for direct measurement and control of process gas composition and detection of contamination in vacuum processes. The ability to monitor gas composition up to 1 mbar has applications in CVD, PECVD, RIE, LPCVD, MOCVD, Vacuum Coating, Plasma Etching, Sputter Deposition, magnetron sputtering, reactive magnetron sputtering.
  • Atmospheric gas analysers, for real time monitoring of gas and vapour composition at ambient pressures. Chemical reaction endpoint monitoring, headspace gas analysis, Thermal analysis (TGA-MS) and evolved gas analysis, Chemical vapour deposition (CVD), Environmental monitoring, fuel cell characterisation.
  • Dissolved gas analyser for measurement of dissolved gas species in liquid samples.
  • Options for analysis up to 30 Atmospheres (30 Bar), gas flow switching systems for multi-stream analysis.
  • Retrofit options for Thermogravimetric systems (TG-MS, TGA-MS) to allow evolved gas analysis on existing TG systems.
  • Integrated systems for specialist applications: for example; Multiple cell permeation test apparatus, XBS flux monitor for MBE applications, desorption analysers, SIMS workbench for surface analysis, LoMASS spectrometers for Hydrogen Isotope detection.
