The Nu Perspective IS stable isotope ratio mass spectrometer is designed to measure isotopic clumping in gas species with high sensitivity, linearity and accuracy. Here, we present a technique for measuring the CO2 isotopologues (masses 44-49) on a Perspective IS at enhanced mass resolving power. The high-resolution option enables users to resolve interference peaks on clumped CO2 isotopologues, particularly useful for data accuracy on Δ48. Note that users can switch between high and normal resolution modes on a Nu Perspective IS for different applications.
