What Is a Certificate of Analysis?
A Certificate of Analysis, commonly called a COA, is a document that provides information about the testing and characteristics of a research compound. It may include details such as compound identity, purity, testing method, batch number, and date of analysis.
COAs help researchers review available quality information before selecting a product for laboratory use.
Important Information to Check
When reviewing a COA, look for:
- Product or compound name
- Batch or lot number
- Purity percentage
- Testing date
- Laboratory name
- Testing methods used
- Identification or verification results
The batch number on the certificate should match the batch number of the product whenever batch-specific documentation is provided.
Common Testing Methods
High-Performance Liquid Chromatography, commonly known as HPLC, may be used to assess purity and detect components within a sample.
Mass spectrometry may be used to help confirm compound identity by analysing molecular characteristics.
Testing methods provide different types of information, so a complete report may include more than one analytical method.
Why Batch Information Matters
Research compounds may be produced in separate batches. A certificate associated with one batch should not automatically be treated as evidence for every future batch.
Clear batch identification improves traceability and helps researchers determine which report relates to the product being reviewed.
Review Documentation Carefully
A purity percentage alone does not provide every detail about a research compound. Researchers should also review identity verification, testing methods, laboratory information, dates, and batch references.
Biohacking Elite is working to make available product documentation easier to access from the relevant product pages.
A practical COA review example
The following is an illustrative documentation check, not a Biohacking Elite test certificate or batch result.
| Document detail | Example | Review decision |
|---|---|---|
| Lot match | Container says EXAMPLE-A; report says EXAMPLE-B | Ask for the report associated with EXAMPLE-A |
| Analytical result | A purity value appears without a method | Request the method and supporting result before interpreting the percentage |
| Identity evidence | A purity result is present; no identity result is listed | Do not infer identity from that percentage alone |
| Date and scope | A dated report covers a particular sample | Record which sample and batch were tested; do not treat the date as an expiry date |
Questions to resolve before relying on a report
Does one COA cover every lot? Match the documentation to the actual lot being reviewed. A report for a different lot leaves a traceability gap.
What if a test is missing? Record it as unreported. Do not convert an absent result into a passing result or an assurance of suitability.
For related explanations, read what purity percentage means and the storage and handling guide.
