Stable isotope analysis relies on the simultaneous or near-simultaneous measurement of two individual species. In the case of the Picarro G1101-i and G2101-i gas analyzers, these two species are ¹²C¹⁶O₂ and ¹³C¹⁶O₂, which we denote ¹²C and ¹³C for simplicity. In the G1101-i,…

The Picarro G1101-i and G2101-i gas analyzers provide field measurements of the stable isotope ratio d¹³CO₂ with a precision of 0.3 permil in five minutes. In an isotope ratio mass spectrometry (IRMS) laboratory, it is customary to dry the samples to very low dew points (< - 45C) prior to isotope analysis. For field work, however, drying the…
