TOC Calculator

Formula Inputs

Use whole-number atom counts. Leave a field at 0 if that element is not present in the molecule.

TOC basis: carbon mass in the molecular formula divided by total molecular weight. Carbon mass uses 12.011 g/mol per carbon atom.

Understanding the calculation

Theoretical organic carbon calculations are performed, using the following formula:
