Product and batch identity
Product name, grade, batch or lot number, manufacturing date and other traceability details.
Batch-specific analytical document
Certificate of Analysis built around the actual product batch and test results.
A Certificate of Analysis should show what was tested for a defined batch, the applicable specification and the reported result. The CoA workflow begins by confirming the product, batch, required parameters and whether reliable laboratory data already exists.

Assessment areas
What information belongs in a useful Certificate of Analysis?
The exact parameters differ by product. The document must remain traceable to the batch, specification and analytical evidence used.
Required parameters
The physical, chemical or microbiological characteristics the requesting party expects to see.
Specification limits
Target, minimum, maximum or pass/fail criteria for each listed parameter.
Test methods
The method, standard or internal procedure used to generate the analytical result.
Actual results
Measured values or outcomes taken from genuine test records for the defined batch.
Authorisation details
Issue date, authorised signatory details and any relevant laboratory reference.
Scope boundaries
Clear inputs, clear output and no unsupported claims.
The assessment confirms what can be completed from the available evidence and what requires separate testing or confirmation.
What we need to prepare the CoA
- Exact product and grade
- Batch or lot identification
- Buyer specification or required parameter list
- Existing laboratory report or internal QC results
- Applicable test methods where known
- Manufacturer and issuing details
What cannot be added without evidence
- Fabricated analytical values
- Results copied from a different batch
- Unsupported “pass” statements
- A laboratory accreditation claim not held by the issuer
- Parameters that were not tested
- Guaranteed buyer or regulatory acceptance
A CoA is only credible when the results can be traced to actual analysis of the stated batch or to a documented quality-control process. If tests are missing, the laboratory scope must be completed before final values are entered.
How it works
From requirement to final document in four steps.
Define the batch and purpose
Confirm the exact product, batch and who requested the CoA.
Confirm required parameters
Share the specification, checklist or buyer-required test list.
Review or arrange test data
Use available verified results or define the required laboratory scope.
Prepare the batch CoA
Receive the digital CoA based on the confirmed evidence and format.
