Documentation-first quality

Quality You Can Verify.

Quality begins with transparency. Pure Northern Peptides is committed to providing clear product documentation and analytical testing information so researchers can make informed decisions about the materials they select.

Know the product. Know the batch. Review the documentation.

Why testing matters

More Than a Number

A purity percentage is only one part of understanding a research material. Analytical documentation can provide important information about the identity, purity, testing methodology, and specific batch being evaluated.

Identity

Helps establish that the material analyzed corresponds to the expected compound.

Purity

Provides analytical information about the composition of the tested sample.

Analytical method

Clearly displays the testing methodology reported by the laboratory, such as HPLC or mass spectrometry, when applicable.

Batch traceability

Connects documentation to the corresponding product lot or batch whenever that information is available.

COA guidance

What Is a Certificate of Analysis?

A Certificate of Analysis, or COA, is documentation reporting the analytical findings for a tested sample. Depending on the analysis performed, a COA may contain information such as sample identification, testing method, purity results, analytical data, testing date, and laboratory information.

How to Read a COA

Information available can vary depending on the test and laboratory.

Product/sample identification
Batch or lot number
Testing laboratory
Date tested
Analytical method
Reported purity
Identity or molecular information, when tested
