Development of an infrared diagnostic instrument for the measurement of CO2 isotope ratios in breath

Stable CO2 isotope breath test are established as a valuable tool in diagnostic and investigate medicine. The instrument conventionally used is an Isotope Ratio Mass Spectrometer, however, the expensive and complexity of such an instrument severely restricts the widespread and routine use of isotope tests. To realize their full potential an alternative instrument which is reliable, uncomplicated, insensitive to environmental and component fluctuations and affordable is required.
