Short summary
In this study, we tested seven N2O analyzers from five different companies and compared the results with established techniques. The test protocols included the characterization of the short-term and long-term repeatability, drift, temperature dependence, linearity and sensitivity to water vapor. All of the analyzers showed a standard deviation better than 0.1 ppb for the 10-min averages. Some analyzers would benefit from improvements in temperature stability and water vapour correction.
