▶ 📝 Notes
* Gas standard concentration: standard gas is diluted to about 50 ppb, NO2 is calibrated by gas phase titration * Gas standard confidence interval: VSL Primary Reference Material: 20.01 +/- 0.1 micomol/mol * for the ozone instrument and metereology instrument the same modules as for https://cigas-box.fz-juelich.de/login/objects/61 were added, if this is not correct add new ozone and metereology instruments and add those.
