How to read this report
- Purity (HPLC)
- Of the peptide material, how much is the exact target compound. This is the headline quality number.
- Total & single impurities
- The small fraction of related peptide by-products. Lower is better.
- Peptide content
- How much of the total powder is peptide versus the bound water and salt it is stored in. The remainder being water and salt is normal for a freeze-dried peptide, not a quality issue.
- Mass spectrum
- Confirms the measured molecular weight matches the target, proof the vial holds the compound named.
- Residual solvents, endotoxin, water
- Cleanliness checks: manufacturing solvents cleared, contamination within limits, and the powder properly dried.
- Pass
- Every result falls inside its listed specification.
