We present a so called micro total analytical system (μTAS) for the measurement of low nitrogen monoxide (NO) concentrations in gas flows. The measurement principle is based on the chemiluminescent reaction of NO with ozone (O3). The presented system scales down this measurement principle into the realm of micro fluidics and micro sensors. Low temperature co-fired ceramics (LTCC) have proven to be the ideal technology for the realization of a μTAS, as they offer high chemical and thermal stability as well as high degree of freedom of design. The system consists of 4 components: an ozone generator, an ozone concentration measurement via UV transmission, a chemiluminescent detection (CLD) chamber, and an exhaust gas treatment. The ozone generator is a micro plasma device in which ozone is produced by a dielectric barrier discharge (DBD) mechanism. From the generator the ozone is fed into a chamber with an optical port, where the concentration is determined by UV transmission measurements. Then it is brought...
