A comparison table places chromatographic purity and net peptide content in one column. Both are percentages, but the reports define their denominators differently. How should the table be repaired?

Create separate columns for the quantity measured, method, units and denominator. Do not subtract the two percentages as though they represented a disagreement about the same measurement.
