COA Library: Batch Certificates of Analysis
Need help interpreting identity, HPLC purity, mass spectrometry, and lot details? Read our laboratory reference guide: How to read a peptide COA.
Batch-specific Certificates of Analysis from third-party laboratories will be posted here as they become available, matched to the batch number on the vial. Questions? Email support@zenwelllabs.com.
Why Batch-Specific COAs Matter
A batch-specific COA lets researchers match a report to the material on hand.
HPLC Purity Analysis
When a COA is posted, it reports the HPLC (High Performance Liquid Chromatography) purity measured for that batch.
Third-Party Reports
As reports are completed, each certificate posted here names the independent laboratory that performed the testing.
Transparency First
Each report is posted here as it becomes available.
How does Zen Well Labs handle batch-specific COAs?
Zen Well Labs posts third-party Certificates of Analysis to this library as reports become available, each matched to the batch number on the vial so researchers can tie the document to the material in hand. When a report is posted, it shows the HPLC purity measured for that batch and names the laboratory that ran the test. If a report for your batch isn’t listed yet, email support@zenwelllabs.com with the batch number.
