DeltaMass — Isotopic Ratio Tool
Isotopic ratio calculator for Agilent ICP-MS MassHunter data.
Features
- GUM-compliant uncertainty budgets
- Mass bias correction (Russell's law)
- SSB bracketing sequences for Tl, U, Sr, Pb, Li, B and more
- Demo mode with synthetic IR batch data
- 100% client-side — your data never leaves your device
How It Works
Upload your MassHunter CSV exports and DeltaMass will parse the batch structure, compute isotopic ratios with full GUM uncertainty propagation, and apply mass bias corrections using Russell's exponential law.
