RELEASE This lot has passed independent third-party laboratory analysis and has been released under AMINOSWORK internal quality specifications.
HPLC Purity %

HPLC purity represents the relative area percentage of the dominant chromatographic peak. Minor variation (e.g., 98–99%) is normal across laboratories. All released batches meet AMINOSWORK standards.

Mass Spectrometry (MS)

MS analysis confirms the molecular weight. The observed mass must match the theoretical mass of the peptide sequence to confirm its Identity.

Pass/Fail Indicators

"PASS" means all internal specs met for purity, identity, and appearance. "FAIL" or "QUARANTINE" means rejected.

Conditional Testing

Some lots have extra tests like moisture or endotoxin. Blank or "N/T" means not required for release of that batch.
