report.
Your lot number is printed on the vial and on the packing sheet. Enter it below to see exactly what the independent laboratory reported for that material — not a summary, and not a different lot.
Sample records available: AMP-SAMPLE-0114 · AMP-SAMPLE-0207 · AMP-SAMPLE-0331 · AMP-SAMPLE-0402
No certificate matches that lot number. Check the vial label, orcontact us with a photograph of it.
What each figure means
- Chromatographic purity
- Main-peak area over total integrated area by RP-HPLC at 214 nm. This is the number most suppliers quote — and often the only one.
- Observed vs theoretical mass
- Confirms identity. If these two do not agree, the material is not the compound named on the vial, however pure the chromatogram looks.
- Net peptide content
- The share of vial mass that is actually peptide, rather than counter-ion, residual solvent and water. A high-purity peptide can still have low net content.
- Residual moisture
- Water drives hydrolysis. Low moisture is what makes a stated storage life meaningful.
