Data precision is crucial in stable isotope measurements. Paradoxically, and annoyingly, the uncertainty on CF-IRMS is highly sensitive to small variations in lab temperature. In this talk, an investigation of open-split CF-IRMS datasets lead to the identification of a relationship between small variations in lab temperature and IRMS results. Examples of how to measure, estimate and track the impact of lab temperature on the data is presented. Finally, a simple solution to partially account for these variations is proposed.
