Rapid Communications in Mass Spectrometry (2017) , V31 (12), pp1057–1066, doi: 10.1002/rcm.7878

Goal: Clumped isotope analyses (Δ47) of carbonates by dual inlet (DI) mass spectrometry require long integration times to reach the necessary high precision due to the low abundance of the rare isotopologue 13C18O16O. We tested an improved analytical workflow that significantly reduces the sample sizes and total analysis time per sample while preserving precision and accuracy.

Geochimica et Cosmochimica Acta (2003), V67 (3), pp. 325–343, doi: 10.1016/S0016-7037(02)00965-1

Goal: We describe a method for measuring the 40Ar/36Ar ratio and the 84Kr/36Ar ratio in air from bubbles trapped in ice cores. These ratios can provide constraints on the past thickness of the firn layer at the ice core site and on the magnitude of past rapid temperature variations when combined with measured 15N/14N. Both variables contribute to paleoclimatic studies and ultimately to the understanding of the controls on Earth’s climate.
