Abstract

A gas-sensitive sensor membrane for the determination of gas concentrations in gas mixtures is proposed. Also proposed are a method and an apparatus for determining gas concentrations based on the change in the electromagnetic radiation absorption properties and/or the optical refraction index of an indicator substance, contained in the sensor membrane, which interacts with the gas to be determined.
