Short summary

Oxygenated volatile organic compounds (OVOCs) are difficult to measure in the atmosphere due to their high reactivity and low concentrations. This hinders our understanding of their impact on air quality and climate. Therefore, we have developed a field-deployable instrument capable of providing isomer-resolved measurements of OVOCs in the ambient air. Its performance is assessed through data collected both in the laboratory and during two field studies.
