Peptide COAs and Batch Verification
Understand how a peptide certificate of analysis should connect analytical evidence to a specific batch, product and controlled release record.
Direct answer: A peptide certificate of analysis is useful only when it can be linked to the exact supplied batch and its underlying analytical records. Product identity, chromatographic purity and quantitative content are separate questions and should not be collapsed into one headline percentage.
What makes a COA batch-specific?
The certificate should contain identifiers that match both the physical label and the supplier’s controlled inventory record. Product name alone is insufficient because the same product can exist across multiple lots and document versions.
Which analytical fields should be separated?
Identity, chromatographic purity, content and any microbiological or endotoxin attributes require their own methods, results and acceptance criteria. A field should remain unpublished when approved source evidence is unavailable.
How should document versions be controlled?
Corrections should preserve the earlier record, reason for change, effective date and approving authority. Silent replacement weakens the evidence chain because a buyer can no longer determine which document supported an earlier decision.
How Lock’d In handles unreleased records
Pending documents are labelled as pending rather than presented as completed analysis. Demonstration records are explicitly separated from released batch evidence.
