Analox's Centralised atmosphere analyser

Analox’s Centralised Atmosphere Analyser (AA) can monitor up to 30 different gases from various locations around the boat. This is ideal for nuclear boats which need to sample a large number of gases at low concentrations. The AA is typically installed in a central location and supplied with sample lines from a number of locations around the boat.


Multiple analysers can be connected together to provide system redundancy.The AA provides real-time continuous monitoring of life support gases such as oxygen, carbon dioxide, carbon monoxide, hydrogen and refrigerants. Non-standard gases are also continually monitored, but generally only displayed on request. These include methanol, hydrogen cyanide, hydrogen chloride, oxides of nitrogen, sulphur dioxide and specific hydrocarbons.

The gases are detected by using a combination of sensor technologies; a mass spectrometer and FTIR (Fourier Transform Infra Red) analyser, which offer the following  benefits:

  • ideal for monitoring low (ppm) concentrations of trace gases
  • can be programmed to look at new gas species as they become of interest through the boat’s operational life
  • has potential to identify unknown pollutants in the atmosphere by doing a mass scan

Besides, Analox also provides other air monitoring systems such as system monitoring CO, CO + (COSAMS, COSAMS +) ...
