chromatoPy interface

chromatoPy

chromatoPy (Otiniano et al., 2025), is a peak integration tool that enables rapid quantification of compounds measured via chromatography.

macOS install note: After downloading the DMG, open it and drag chromatoPy-desktop.app into your Applications folder. Then open Terminal and run:

xattr -dr com.apple.quarantine /Applications/chromatoPy-desktop.app

Pysotope

pysotope is a python package for processing isotopic data measured via GC-IRMS (δ2H, δ13C) and EA (δ13C, δ15N). Corrections for drift (time), linearity (amount), methanol (for FAME derivatization), and reference standards (e.g., VSMOW). We incorporate a number of methods for identifying coherent trends in measurement standards, enabling accurate isotopic measurements even at low concentrations.
