01 / Understand

One report.
Different questions.

A Certificate of Analysis, or COA, records results for a submitted sample. Read each measurement on its own terms.

Walk through a report →
01

Identity

Which material was detected?

Read the identity method and reference used. A name on a label and an analytical identification are separate pieces of information.

02

Purity

What does the analytical profile show?

Read the reported percentage with its method. Purity alone does not tell you how many milligrams are in the container.

03

Measured content

How much was measured?

Compare the measured amount, units and labeled size. A concentration and a total amount describe different quantities.

04

Additional testing

What else was checked?

Look for the actual panel, methods and reporting limits. Only the tests listed on that report establish what was examined.

How to read and verify a batch COA

Start with the report for your material, then check the details.

  1. Match the product, size and lot

    Compare the report with your vial label. A report for another size or lot is not a substitute for the report associated with your material.

  2. Check the date and laboratory record

    Open the full PDF, then use its access code or verification link to check the laboratory record. The directory includes historical batches; a newer test date does not identify the lot in your order.

  3. Read each result separately

    Purity, measured content and identity answer different questions. Review the reported methods, units and limits as well as the result. A purity percentage alone does not state how many milligrams are in a vial.

  4. Keep the report with your research records

    Record the lot and access code alongside the material you received. If the label and report do not match, contact Prism Labs for help locating the corresponding documentation.
