01
What peptide purity information means
Purity is one part of a peptide product specification. It generally describes the proportion of the target component detected under a stated analytical method and should be reviewed together with the method, sample details, and other available documentation.
02
Common analytical methods
High-performance liquid chromatography is commonly used to evaluate chromatographic purity, while mass spectrometry can support identity assessment by comparing observed and expected mass information. These methods answer different questions and should not be treated as interchangeable.
- Review the stated test method.
- Match documents to the relevant product and batch.
- Ask for clarification when results or units are unclear.
03
Review purity in purchasing context
Research buyers should define their documentation and purity requirements before requesting a quotation. The supplier can then confirm what information is available for the selected product, specification, and batch.
