A report can show high purity while the measured quantity differs from the label. Those findings are not interchangeable. Purity describes the composition of what was detected; quantity addresses how much was measured in the submitted sample.
If a summary keeps only the more flattering percentage, the reader loses the second result and its denominator. A useful post should name each test, reproduce its measured value, preserve the label claim, and avoid turning one sample into a statement about every vial.
