Short summary
A miniaturized, field-applicable sensor system was developed for the measurement of low hydrogen (H2) concentrations in air. The sensor system is based on the application of a newly developed miniaturized coulometric detector with gas chromatographic (GC) pre-separation after injection. By optimizing all operational parameters, it was possible to conduct reproducible and 100 % selective H2 measurements with more than 90 % analyte turnover compared to Faraday's law.
