Research product integrity is maintained by preserving identity, purity, and documentation from manufacturing through delivery and storage. In laboratory purchasing, this means confirming that each lot is supported by a clear certificate of analysis (COA), traceable batch information, and appropriate analytical data.
Key controls
- Identity verification: Use methods such as HPLC and mass spectrometry to confirm composition and detect unexpected impurities.
- Documentation review: Check lot number, test date, purity data, and any stated storage conditions against internal acceptance criteria.
- Packaging and shipping: Inspect seals, labels, and shipment condition to reduce risk of contamination or degradation during transit.
- Storage management: Store materials under the conditions specified by the supplier and limit repeated exposure to light, moisture, and temperature fluctuation.
- Record retention: Maintain COAs, receiving records, and test results to support traceability and audit readiness.
For laboratory research, products should be handled as research use only and are not intended for human consumption.
