Certificate of Analysis
Independent COA services backed by analytical data, documented methods, and clear reporting for peptide and research-compound samples.
What a COA Should Show
A professional Certificate of Analysis should connect the sample, the methods used, and the reported results in a way that supports traceability and review.
Lab Centro positions COA services around sample identification, lot or batch reference, analytical scope, result reporting, and documentation that helps clients evaluate purity, identity, and supporting quality data.
Key Elements
What Clients Review
COA content should be practical, readable, and tied to actual analytical work rather than generic claims.
Sample Identification
Clear reference to the submitted sample, client identifier, and lot or batch details helps maintain chain of custody and reporting accuracy.
Analytical Scope
The report should state which tests were performed, such as purity, identity, endotoxin, heavy metals, sterility, residual solvents, or custom analytical work.
Results and Criteria
Results should be presented in a structured format that supports comparison against the requested specification or acceptance criteria when provided.
Supporting Documentation
Where applicable, clients may request supporting analytical data, method references, and related documentation to strengthen review and verification.
Use Cases
Common COA Applications
