What DELTALab does
DELTALab is a free desktop application for processing and standardising clumped isotope data. It handles clumped isotopes (Δ47 and Δ48) together with bulk δ13C and δ18O, and it imports the files labs already have: Thermo Isodat .did files, Qtegra CSV exports and legacy Easotope databases.
It corrects the background, standardises your replicates against reference materials such as ETH-1 to ETH-4 and IAEA-C1/C2, and converts Δ47 to temperature with the calibration you choose. Replicate and sample tables, diagnostic plots and export reports come with it. The clumped isotope maths gives the same numbers as D47crunch and D47calib. DELTALab is made for stable-isotope geochemistry labs.
