Short summary
Due to technological advances clumped-isotope studies have gained importance in recent years. Typically, these studies are performed with high-resolution isotope ratio mass spectrometers (IRMSs) along with a changeover-valve-based dual-inlet system (DIS). We are taking a different approach, namely performing clumped-isotope measurements with a compact low-resolution IRMS with an open-split-based DIS. Currently, we are working with pure-oxygen gas for which we are providing a proof of concept.
