New multigas measurement technology has been developed as part of and in parallel with a series of projects for the European Space Agency (ESA). Based on well-established Fourier transform infrared (FTIR) spectroscopy and novel calibration and analysis methods, ESA's Analysing Interferometer for Ambient Air (ANITA) system has successfully demonstrated continuous air quality monitoring on the International Space Station (ISS). ANITA performed automatic multigas measurements in quasireal time with high sensitivity, specificity, stability and reliability. The novel analysis techniques are well suited also for general workplace air monitoring, industrial processes and other multicomponent measurement tasks.

Raman based gas sensing can be attractive in several industrial applications, due to its multi-gas sensing capabilities and its ability to detect O 2 and N 2 . In this article, we have built a Raman gas probe, based on low-cost components, which has shown an estimated detection limit of 0.5 % for 30 second measurements of N 2 and O 2 . While this detection limit is higher than that of commercially available equipment, our estimated component cost is approximately one tenth of the price of commercially available equipment. The use of a resonant Fabry-Pérot cavity increases the scattered signal, and hence the sensitivity, by a factor of 50. The cavity is kept in resonance using a piezo-actuated mirror and a photodiode in a feedback loop. The system described in this article was made with minimum-cost components to demonstrate the low-cost principle. However, it is possible to decrease the detection limit using a higher-powered (but still low-cost) laser and improving the collection optics. By applying these improvements, the detection limit and estimated measurement precision will be sufficient for e.g. the monitoring of input gases in combustion processes, such as e.g. (bio-)gas power plants. In these processes, knowledge about gas compositions with 0.1 % (absolute) precision can help regulate and optimize process conditions. The system has the potential to provide a low-cost, industrial Raman sensor that is optimized for specific gas-detection applications.

“…The system's measurement principle is based on the detection of the IR (infrared) absorption features stemming from the different gas molecules' vibration modes. From the measured IR spectra the gas concentrations are derived via sophisticated analysis SW applying optimised, non-linear data-evaluation methods; (compare especially 3,4,5,11 ). The system's capability to measure with a time resolution in the order of minutes allows for the first time to trace the dynamics in the concentrations of trace gases within the ISS atmosphere.…”

Following the successful European precursor mission ANITA1 (Analysing Interferometer for Ambient Air) operating on ISS for 11 months in 2007 and 2008, the next generation system ANITA2 is in the design and breadboarding phase. The ANITA1 data have delivered new and partly surprising results on the dynamics of the crewed cabin atmosphere showing the advantages of an optical sensor with high time resolution. The successor instrument ANITA2 is developed to give a system with significant improvements in sensitivity and instrument characteristics. ANITA2 will be calibrated to detect and quantify simultaneously and quasi on-line more than 30 of the most important trace gases in the cabin atmosphere with automatic operation for three to five years on ISS. ANITA2 will be a maintenance-free, reliable, and compact multi-gas air quality monitor.ANITA2 is like ANITA1 suggested to be an ESA-NASA cooperative programme. It further represents a precursor system for missions e.g. to the Moon and Mars under the manned exploration programme. The following ANITA3 system will be a high performance, maintenance-free measurement unit approaching the size of a shoe box. The paper will report on the newly started ANITA2 development of an instrument breadboard and analysis software pre-developments giving an outlook into the future programmatics. The work described is performed under contract of the European Space Agency ESA.
