Short summary
Here we present the instrument characteristics and field applicability of the newly developed Delta Ray analyzer for stable isotope measurements in CO2. We used this analyzer to measure the concentration and the isotopic composition of CO2 exchange in a managed beech forest for 3 months in autumn 2015. During this period an early frost event occurred and our measurements suggest that this short event strongly influenced the measured isotopic composition of CO2 exchange.
