Chain of custody for research peptide records
The minimum traceability links needed between sample, analytical record, release decision and shipment.
Chain of custody documents who handled a sample, when transfers occurred and which identifiers followed it through analysis and release.
Traceability becomes especially important when analytical samples and commercial units move through different facilities. Reconciliation should connect the submitted sample, lot, report and dispatched material.
A documented exception process is as important as the normal path. Broken seals, identifier conflicts and missing transfer records should stop release until resolved.
Practical review points
- Use durable lot and sample identifiers
- Record transfers and responsible parties
- Reconcile report identifiers to release inventory
- Document storage and dispatch conditions
- Stop release when traceability breaks
