Our various technologies, sensors and analysis devices enable gas analysis that meets the highest demands. The measuring instruments developed by us can be found in a wide range of industrial sectors. In the automotive, environmental, medical and process technology sectors, our customer-specific solutions are successfully in use.
Under our brand TRACE-GAS you will find a variety of our solutions in the field of gas analysis, like NDIR, LAS, PAS, CLD as well as ready-to-use gas analyzers and OEM sensors.
The project objective was the development of a NDIRflex measuring bench with modular design for different cuvette lengths.
The measured values should be accessed via a CAN or rather a serial RS232 communication protocol. Furthermore, it should also be realized a heated cuvette and a Peltier cooling for the thermopile receiver. About a further measuring input, an electrochemical O2 sensor should be evaluated additionally. A further requirement was to determine the flow of the gas to be measured and a pressure or temperature compensation of the measured values.
Our projects in the field of gas analytics are constantly evolving.

The project objective was the development of a compact, well-integrable analyzer module consisting of a long way cell (Herriott) and an laser control electronics for trace gas analysis of N2O. Beside N2O, the gases CO, CO2 and O3 shall be determinable. A fast response time (t90: 1-2 seconds), no cross-sensitivities to other gases, and a low detection limit
of < 10 ppbV are the characteristic conditions that were set on this project.

The project objective was the development of a photoacoustic sensor for the measurement of
NO2 -concentrations in exhaust gases with a detection limit of < 50 ppb using the photoacoustic principle.
A particular challenge was to perform the measurement independently of ambient or flow noise.
Another project goal was to operate the cell in acoustic resonance, for which procedures for stabilization had to be developed (resonance tracking). This allows continuous measurement under gas flow, independent of changes in
temperature or gas concentration.
