Lot identifiers
Each released material label carries a lot identifier. When one is assigned, it also appears in the associated order record, so the material in hand can be traced to its documentation.
Supplied analytical reports
Certificates of Analysis in the COA Library are original documents, reproduced as supplied and labelled as supplied reports. Publication does not by itself establish independent verification or a match to current inventory, so review each document for its sample identity, lot, issuer and analysis details.
How reports are matched
A report is connected to a specific compound, material variant and lot identifier. A product is only shown as having a COA when a supplied report is matched to it, and documents still under review are never counted as available.
No implied results
Where no report is matched, none is implied. A report covers only the tests listed on it; an attribute that is not reported should be treated as not reported.
Private document access
The COA Library opens after you sign in to an ARQEN account with catalog access. Report files are delivered through private, short-lived links rather than public web addresses.
Research use only
Documentation is provided for identification and record keeping in laboratory research. It does not establish suitability for any particular protocol, and materials are not for human or veterinary use.
Reading a report
The Research Library explains how to review a Certificate of Analysis, from identity and purity results to lot matching and test dates. For a question about a specific report, use the contact form and choose Documentation.
