Labs evaluate research product quality standards by reviewing documentation and confirming that analytical results match the supplier’s stated specifications. A practical assessment usually includes:
- Identity verification using mass spectrometry or another orthogonal method
- Purity review based on HPLC or related chromatographic data
- Documentation checks for a complete COA, batch identifier, and test methods
- Traceability review to ensure the lot can be linked to manufacturing records
- Packaging and shipment review for evidence that handling conditions were appropriate
Researchers should also confirm that analytical dates are current, acceptance criteria are clearly defined, and any deviations are documented. When evaluating a product for laboratory use, it is helpful to compare the supplier’s quality statements against internal procurement requirements and study-specific specifications.
