RP-HPLC
Supports chromatographic purity review and should be read with the method, chromatogram, retention information and batch reference.
Peptide Quality Verification
Batch identity, analytical evidence and document consistency for B2B procurement.
Quality Starts With a Defined Specification
A useful peptide quality review compares the buyer-approved product identity, form, specification and packaging brief with the batch documents and supplied material. A COA should not be reviewed as a marketing image in isolation.
Analytical Methods Available
LC-MS
Supports molecular identity review by comparing measured mass information with the expected peptide.
NMR
Can support structural characterisation where included in the agreed analytical package.
Bioburden testing
Available for projects where microbial load information is required by the buyer specification.
Endotoxin testing
Available where the agreed application and buyer specification require endotoxin evidence.
Batch Document Review
- Match the product name, batch or lot reference and testing date.
- Check which test method supports each reported result.
- Confirm that identity and purity are not treated as the same measurement.
- Match vial, bulk powder or OEM packaging records to the same batch reference.
- Clarify any missing fields before approving shipment.
Procurement Boundaries
Testing scope is agreed per project. This page does not imply a certification, fixed specification or universal analytical package. Buyers should request the documents needed for their institution, destination and intended research or manufacturing use.
