Use this glossary while reviewing a research peptide product page or its documents. A laboratory’s definitions and the wording of the actual report take priority when a term is used in a specific method.
Documents
- COA — Certificate of Analysis
An analytical document reporting the tests and results for an identified sample. Match its product, sample, and lot information before using a result.
- SDS — Safety Data Sheet
A document communicating information about a material’s hazards and precautions. It has a different purpose from the sample’s analytical results.
- Report number
The reference used by an issuer to identify a report. Keep it with the complete document so you can specify which report you are asking about.
- Revision
An identified version of a document. The revision label or date helps distinguish an updated document from an earlier copy; record the version you reviewed.
Identifiers and traceability
- Lot or batch number
An identifier assigned to a defined group of material. Check how the supplier’s lot connects to the identifiers on the label and report; similar product names alone do not establish that connection.
- Sample ID
A code identifying a sample in a laboratory’s records. It may differ from the supplier’s lot number. Ask for the connection when it is not clear from the documentation.
- Traceability in a document review
The recorded connection between the product, its lot, the tested sample, and the associated documents. Retain the identifiers and any correspondence needed to understand that connection.
Methods and results
- Test method
The analytical procedure associated with a reported result. Its name, version when provided, and reporting basis help explain what the result describes.
- Purity
A reported measure of the target material relative to other detected or measured components under a stated method. Interpret the percentage using the laboratory’s definition and method.
- Content or quantity
A result describing an amount or defined proportion. Read the units and basis: a mass per vial, a concentration, and a percentage are not interchangeable fields.
- Identity
The question of what the tested material is. Review the stated identification method, the supporting information, and the issuer’s conclusion.
- Specification or acceptance criterion
A stated requirement against which a result can be compared. Read both the criterion and the result, including any qualifications, to understand a reported pass or fail.
- Reporting basis
The context attached to a value, such as per vial or per sample, or the defined calculation behind a percentage. Keep this context with the number whenever you copy a result into your notes.
